For simple linear regression, the explanatory variable is numeric.

Simple linear regression is a statistical method that allows researchers to understand the relationship between two continuous variables. A simple linear regression model is used to represent the relationship between a dependent variable (Y) and an independent variable (X) by making a linear equation of the form

Y = a + bX, where a is the constant, and b is the regression coefficient.

In simple linear regression, the explanatory variable is of numeric type. This statistical method involves the use of two numeric variables, namely the explanatory (independent) variable and the response (dependent) variable, which are analyzed to establish a linear relationship between them.

Answer:

x=10

Step-by-step explanation:

Use pythagorean theorem, a^2+b^2=c^2

24^2 + b^2 = 26^2

576 + b = 676

676-576=100

\(\sqrt{x} 100\)=10

Answer:

x = 10

Step-by-step explanation:

Let b represent x.

Use the Pythagorean Theorem:

\(a^{2} + b^{2} = c^{2}\)

24² + b² = 26²

24² = 576

26² = 676

576 + b² = 676

Subtract 576 from both sides:

b² = 100

Square root of 100:

x = 10

Quadrilateral MNOP is similar to quadrilateral QRST. The measure of side RS is approximately 39.2 units.

If two quadrilaterals are similar, their corresponding sides are in proportion. Therefore, we can set up a proportion between the corresponding sides of quadrilaterals MNOP and QRST as follows:

MN / QR = NO / ST = OP / RS

We are given the lengths of MN, NO, and OP, but we need to find the length of RS. We can solve for RS by rearranging the proportion as follows:

OP / RS = MN / QR

RS = OP / (MN / QR)

We can substitute the given values to get:

RS = 58 / (19 / 13)

Simplifying this expression gives:

RS = 58 * (13 / 19) = 39.241 ≈ 39.2

Therefore, the measure of side RS is approximately 39.2 units.

Step-by-step explanation:

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the middle of the garden measures 30 feet. What is the distance around the perimeter of the garden? 120ft.

The perimeter of the rhombus is P = 120 feet

A Rhombus has four sides of the same length, its perimeter can be determined using the formula Perimeter = 4a, where "a" stands for the side's length.

When the two diagonals of a rhombus are known,

The perimeter = 2√p² + q²

where 'p' and 'q' are the diagonals.

Given data ,

Let the rhombus be represented as ABCD

Let the side length of the rhombus be AB = 30 feet

And , perimeter = 2√p² + q²

And , P = AB + BC + CD + AD

Due to the four triangles' similarity, we may conclude that AC is divided at O. So, we are aware that AO = 15 feet.

In ΔAOD,

(Perpendicular/hypotenuse) = sin 30°

or, 1/2 = 15/AD

otherwise, AD = 15 x 2 = 30 ft

So, AD equals 30 feet.

Given that all of a rhombus' sides are equal and all four of its triangles are the same, we have AB = BC = CD = AD = 30 feet.

On simplifying , we get

P = 4 ( 30 feet )

So , P = 120 feet

Hence , the perimeter is 120 feet

A score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.

To compare the two scores, we can convert them to z-scores, which tell us how many standard deviations a particular value is from the mean. The formula for z-score is:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

For the first score of x = 70 on an exam with μ = 82 and σ = 8, the z-score is:

z = (70 - 82) / 8 = -1.5

For the second score of x = 60 on an exam with μ = 72 and σ = 12, the z-score is:

z = (60 - 72) / 12 = -1.0

The z-score for the first score is lower than the z-score for the second score, which means that the first score is further below its mean than the second score is below its mean. Therefore, we can say that a score of x = 60 on an exam with μ = 72 and σ = 12 is comparatively better than a score of x = 70 on an exam with μ = 82 and σ = 8.

True, The One Way Repeated Measures ANOVA is used when you have a quantitative DV and an IV with three or more levels that is within subjects in nature.

The statement is true and explained as follows:

The One Way Repeated Measures ANOVA is a statistical technique that is used to analyze data from experiments where the same participants are exposed to multiple levels of an independent variable (IV). This type of experimental design is known as a within-subjects design, as opposed to a between-subjects design, where different participants are used for each level of the IV.

One of the main advantages of using a within-subjects design is that it allows for more efficient use of participants. By exposing each participant to all levels of the IV, the variability between participants is reduced, which in turn increases the power of the statistical analysis.

The One Way Repeated Measures ANOVA is specifically used when the dependent variable (DV) is quantitative, meaning that it can be measured using numerical values. Additionally, the IV must have three or more levels, meaning that there are at least three different conditions that participants are exposed to.

The basic idea behind the One Way Repeated Measures ANOVA is to compare the mean scores of the DV across the different levels of the IV while taking into account the fact that the same participants are being used for each level. This is done by calculating the within-subjects variability, which is the variability in the scores of the DV that is due to individual differences between participants. The within-subjects variability is then compared to the between-subjects variability, which is the variability in the scores of the DV that is due to the different levels of the IV.

The statistical output from the One Way Repeated Measures ANOVA includes an F-test, which compares the within-subjects variability to the between-subjects variability. If the F-test is statistically significant, this indicates that there is a significant difference between at least two of the levels of the IV.

In conclusion, the One Way Repeated Measures ANOVA is a useful statistical technique for analyzing data from within-subjects experiments with a quantitative DV and an IV with three or more levels. By taking into account the fact that the same participants are used for each level, the One Way Repeated Measures ANOVA can provide a more efficient and powerful analysis of experimental data.

The assumptions for independent-measures ANOVA include independence of observations, homogeneity of variance, and, to a lesser extent, approximate normality of the populations.

The assumptions underlying independent-measures analysis of variance (ANOVA) are:

b. The observations are independent of one another: This assumption requires that the observations within each group or sample are not influenced by or dependent on the observations in other groups or samples. Independence ensures that the variability observed between groups is not confounded by any systematic relationship between the observations.

c. Each of the populations of scores from which the samples are drawn has the same variance: This assumption, known as homogeneity of variance, requires that the variability or spread of scores within each population is approximately equal. Homogeneity of variance ensures that the comparison of group means is not biased by unequal variability between groups.

d. Each of the populations of scores from which the samples are drawn is normally distributed: This assumption assumes that the distribution of scores within each population follows a normal distribution. However, ANOVA is known to be robust against departures from normality, especially with larger sample sizes. Violations of normality may be acceptable as long as other assumptions, such as homogeneity of variance, are met.

a. The populations from which the samples are taken follow an F distribution: This assumption is not necessary for independent-measures ANOVA. The F distribution is used as the sampling distribution for the test statistic, but it is not an assumption about the populations themselves.

In summary, the assumption about populations following an F distribution is not required.

Analyzing the characteristics of respondents and non-respondents can provide insights into potential biases and help address any discrepancies.

The survey results are at risk for a type of bias known as non-response bias. Non-response bias occurs when a subset of individuals chosen to participate in a survey does not respond, leading to potential differences between the respondents and non-respondents. In this case, the employees in the human resources department who were hired in the past two years are required to respond to the questionnaire within five days.

Non-response bias can arise due to various reasons. Some employees may choose not to participate in the survey because they are dissatisfied or unhappy with their job, leading to a skewed representation of employee satisfaction. On the other hand, employees who are highly satisfied or have positive experiences may be more motivated to complete the survey, leading to an overrepresentation of their views. This can result in an inaccurate picture of overall employee satisfaction within the department.

To minimize non-response bias, the manager could consider implementing strategies such as reminders, follow-ups, or incentives to encourage higher response rates.
