The appropriate inference procedure to estimate the difference in the mean number of units produced by employees who work with and without music playing in the background is D. z confidence interval for a difference in proportions

In this scenario, the appropriate inference approach is to compare the means of two independent samples (workers who work with music and employees who do not work with music) to see if there is a significant difference between them.

The t confidence interval takes into consideration data variability and provides an interval estimate for the genuine difference in means.

Answer:

-x+3

Step-by-step explanation:

3 plus signs so 1+1+1= 3

Answer:

B. - 3 / 2

Step-by-step explanation:

Let,

( x1, y1 ) = ( - 2, 5 )

So,

x1 = - 2

y1 = 5

( x2, y2 ) = ( 4, - 4 )

So,

x2 = 4

y2 = - 4

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope = ( - 4 - 5 ) / ( 4 - ( - 2 ) )

= - 9 / ( 4 + 2 )

= - 9 / 6

Slope = - 3 / 2

Answer:

B

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 2, 5 ) and (x₂, y₂ ) = (4, - 4 )

m = \(\frac{-4-5}{4-(-2)}\) = \(\frac{-9}{4+2}\) = \(\frac{-9}{6}\) = - \(\frac{3}{2}\) → B

Answers are 7/8 and -5/8.

None of the wind gusts (17, 22, 8, 13, 19, 36, and 14) fall below -0.5 or above 35.5, there are no outliers in this data set. Therefore, the correct answer is D) none.

To identify any outliers in the data set, we can use a common method called the 1.5 interquartile range (IQR) rule.

The IQR is a measure of statistical dispersion and represents the range between the first quartile (Q1) and the third quartile (Q3) of a dataset. According to the 1.5 IQR rule, any value below Q1 - 1.5 × IQR or above Q3 + 1.5 × IQR can be considered an outlier.

To determine if there are any outliers in the given data set of wind gusts (17, 22, 8, 13, 19, 36, and 14), let's follow these steps:

Sort the data set in ascending order: 8, 13, 14, 17, 19, 22, 36.

Calculate the first quartile (Q1) and the third quartile (Q3).

Q1: The median of the lower half of the data set (8, 13, 14) is 13.

Q3: The median of the upper half of the data set (19, 22, 36) is 22.

Calculate the interquartile range (IQR).

IQR = Q3 - Q1 = 22 - 13 = 9.

Step 4: Identify any outliers using the 1.5 IQR rule.

Values below Q1 - 1.5 × IQR = 13 - 1.5 × 9 = 13 - 13.5 = -0.5.

Values above Q3 + 1.5 × IQR = 22 + 1.5 × 9 = 22 + 13.5 = 35.5.

Since none of the wind gusts (17, 22, 8, 13, 19, 36, and 14) fall below -0.5 or above 35.5, there are no outliers in this data set.

Therefore, the correct answer is D) none.

Step-by-step explanation:

The probability that you earn 10 points, then 5 points, then 10 points is 0.000356 or 0.0356%.

We can approach this problem by using the multiplication rule of probability, which states that the probability of two or more independent events occurring together is the product of their individual probabilities.

First, we need to find the probability of drawing a card worth 10 points. There are 16 cards in the deck that are worth 10 points (4 tens, 4 jacks, 4 queens, and 4 kings) out of a total of 52 cards. Therefore, the probability of drawing a card worth 10 points on the first draw is 16/52 or 4/13.

Next, we need to find the probability of drawing a card worth 5 points. There are four cards in the deck worth 5 points, all of which are fives. Therefore, the probability of drawing a card worth 5 points on the second draw is 4/51, since there are only 51 cards left in the deck.

Finally, we need to find the probability of drawing another card worth 10 points on the third draw. Since we already drew a card worth 10 points, there are only 15 such cards left in the deck out of 50 remaining cards. Therefore, the probability of drawing another card worth 10 points on the third draw is 15/50 or 3/10.

Using the multiplication rule, we can find the probability of earning 10 points, then 5 points, then 10 points as follows:

P(10 points, 5 points, 10 points) = P(10 points on first draw) * P(5 points on second draw) * P(10 points on third draw)

P(10 points, 5 points, 10 points) = (4/13) * (4/51) * (3/10)

P(10 points, 5 points, 10 points) = 12/33,726

P(10 points, 5 points, 10 points) is approximately 0.000356 or 0.0356%.

Step-by-step explanation:

Equation : (x - 4)² + (y + 3)² = 4.

A bell-shaped histogram is a type of graph that displays a normal distribution, which is a probability distribution that is symmetrical and has a characteristic bell shape.

The bell-shaped histogram is created by plotting the data on a horizontal axis and the frequency or probability on a vertical axis. The data points are grouped into intervals called bins, and the number of data points that fall into each bin is plotted as a bar. The bars are typically drawn adjacent to one another and connected with lines to create a continuous curve that represents the normal distribution.

The resulting histogram will have a characteristic bell shape, with a high point at the mean, and decreasing frequency or probability as the values move away from the mean in either direction. The width of the curve is determined by the standard deviation of the data, with wider curves indicating greater variation in the data.

The bell-shaped histogram is commonly used in statistical analysis to represent normally distributed data, such as the heights or weights of a population, test scores, or other measurements that tend to cluster around a central value with a predictable range of variation.

the claim aligns with the null hypothesis, as both assert the absence of an effect, difference, or relationship between variables.

The claim and the null hypothesis are the same when the claim being made is that there is no significant difference or relationship between variables or that there is no effect or impact of a particular factor. In other words, the claim asserts that the null hypothesis is true.

For example, if the null hypothesis (H₀) states that there is no difference between the means of two groups, the corresponding claim would be that the means are indeed equal. Similarly, if the null hypothesis states that there is no correlation between two variables, the claim would be that there is indeed no significant correlation.

In such cases, the claim aligns with the null hypothesis, as both assert the absence of an effect, difference, or relationship between variables.

The length of the arc in simplest form is 26.16.

A circle's arc is referred to as a portion or section of its circumference. A chord of a circle is a straight line that might be created by joining the arc's two ends. An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve contains an arc. A circle is the most common example of an arc, yet it can also be a section of other curved shapes like an ellipse.

Given,

Central angle = 5π/6

r = 10

Equating in formula,

central angle/2π = Arc length/2πr

5π/6÷2 = arc length/2π(10)

5π/12 = arc length/2π(10)

Arc length = 20π(5/12)

Arc length = 8.3(3.14)
