If we reject the null hypothesis, it suggests that the test statistic is more extreme than the critical value, the correct answer is b.

When we conduct a hypothesis test, the null hypothesis assumes that there is no significant difference or relationship between the variables being tested. The alternative hypothesis, on the other hand, suggests that there is a significant difference or relationship. In hypothesis testing, we compare the test statistic (calculated from our sample data) to the critical value (determined based on the significance level chosen).

If the test statistic is more extreme than the critical value, it means that the observed data is highly unlikely to occur under the assumption of the null hypothesis. This leads us to reject the null hypothesis in favor of the alternative hypothesis. By rejecting the null hypothesis, we conclude that there is evidence to support the presence of a significant difference or relationship between the variables.

rejecting the null hypothesis indicates that the test statistic is more extreme than the critical value, providing evidence for a difference or relationship between the variables being tested.

Answer:

$3.10

Step-by-step explanation:

The taxable income of Marcel and Stephanie is less than their annual salary because they are allowed to make deductions from their income before calculating their taxable income.

These deductions include contributions to retirement plans, health insurance premiums, and other eligible expenses. The amount of deductions varies depending on factors such as the type of expense and the individual's tax filing status.

Thus, the taxable income is the amount of income that is subject to taxation, and it is generally lower than the individual's annual salary. In the case of Marcel and Stephanie, their taxable incomes are calculated by subtracting their deductions from their respective annual salaries.

Answer:

They are 5 and -4

The given equation's zeroes are 5 and -4.

In quadratic equations, it is a polynomial with a degree of 2 or the maximum power of the variable is 2. It has two options because its maximum power is two.

Given the equation y=3(x-5)(x+4). The zeroes will be calculated as:-

y = 3 (x - 5 ) ( x + 4 )

y = 0

Solve the equation for the zeroes as below,

3(x-5)(x+4) = 0

( x - 5 ) = 0

x = 5

x + 4 = 0

x = -4

Therefore, the zeroes are 5 and -4.

A factorial design with 2^4 levels and 7 replicates was used to study the effects of factors on putting accuracy. ANOVA revealed a significant model. The factors that significantly affect putting performance were determined, and recommendations were made to the golfer to improve their putting.

To determine if this is a valid model, we need to perform an analysis of variance (ANOVA) on the data. This will allow us to determine if the means of the groups are significantly different from each other, and if the factors have a significant effect on the dependent variable.

Before performing the ANOVA, we can check for normality of the data using a normal probability plot or a histogram. If the data is not normally distributed, we can consider a transformation, such as a logarithmic or square root transformation, to improve the model.

Assuming that the data is normally distributed, we can perform an ANOVA to determine if the model is valid.

To determine which factors significantly affect putting performance, we need to look at the main effects and interaction effects of the factors. The main effects are the effects of each factor on the dependent variable, while the interaction effects are the effects of combinations of factors on the dependent variable.

We can use a statistical software package, such as SPSS or R, to perform the ANOVA and calculate the main effects and interaction effects.

Based on the results of the ANOVA, we can make recommendations to the golfer to improve their putting. For example, if we find that the length of putt significantly affects putting performance, we can recommend that the golfer focus on practicing putts of a certain length.

Similarly, if we find that the type of putter significantly affects putting performance, we can recommend that the golfer try different putters to find one that works best for them.

Answer:

x=9

Step-by-step explanation:

You want to start by taking the problem step by step.

First subtract 6 from 51. Which will get you to 45. Then think what times what equals 45, or just divide 45 by 5. This works for any problem like this! Hope this helped!

Answer:

\( \bf \huge9\)

Step-by-step explanation:

⟼ 6 + 5x = 51

step 1 : Simplify both sides of the equation.

⟼ 5x + 6 = 51

step 2 : Subtract 6 from both sides.

⟼ 5x + 6 - 6 = 51 - 6

⟼ 5x = 45

step 3 : Divide both sides by 5

⟼ 5x / 5 = 45 / 5

⟼ x = 45 / 5

⟼ x = 9.

∴ x = 9.

lets take x = 9.

⟼ 6 + 5 (9) = 51

⟼ 6 + 5 × 9 = 51

⟼ 6 + 45 = 51

⟼ 51 = 51.

Y and x have a proportional relationship, and y = 24 when x = 16 What is the value of x when y = 36?

If y is proportional to x, then;

y = kx

24 = 16k

k = 24/16

k = 1.5

Recall that y = kx

36 = 1.5x

x = 36/1.5

x = 24

Step-by-step explanation:

multiply to remove the fraction, then set equal to 0 and solve

The missing part of the equation is \(-7.0\times10^4 s^2kg⋅m^2 / 1000000.\)

To fill in the missing part of the equation, let's analyze the given information and the desired conversion. The equation is:

\((-7.0\times 10^4 s^2g⋅m^2)\cdot \pi = ? s^2kg\cdot m^2\)

In this equation, we have a quantity expressed in\(s^2g\cdot m^2\) units on the left-hand side. To convert it to \(s^2kg\cdot m^2\) units, we need to multiply it by a conversion factor.

To perform the conversion, we can use the fact that 1 kg is equal to 1000 g. Therefore, the conversion factor we need is:

1 kg / 1000 g

To ensure that the units cancel out correctly, we need to square this conversion factor because we have \(s^2g\cdot m^2\) on the left-hand side. So the missing part of the equation is:

\((-7.0\times 10^4 s^2g\cdot m^2)\cdot \pi = (-7.0\times 10^4 s^2g\cdot m^2)\cdot (1 kg / 1000 g)^2\)

Simplifying this expression, we get:

\((-7.0\times10^4 s^2g\cdot m^2)\cdot \pi = -7.0 \times10^4 s^2kg\cdot m^2 / 1000000\)

Therefore, the missing part of the equation is \(-7.0 \times 10^4 s^2kg\cdot m^2 / 1000000.\)

The calculation of the 99% confidence interval is 26.57 and 33.43.

We are given that;

Standard deviation = 20

Number of convicted criminals= 225

Now,

1. Calculate the standard error of the mean using the formula:

\($$SE = \frac{SD}{\sqrt{N}}$$\) where SE is the standard error,

SD is the standard deviation and N is the sample size. In this case, SD = 20 and N = 225,

\(so $$SE = \frac{20}{\sqrt{225}} = \frac{20}{15} = 1.33$$\)

2. Calculate the 95% confidence interval using the formula:

\($$\bar{x} \pm z_{\alpha/2} \times SE$$ where $\bar{x}$ is the sample mean, $z_{\alpha/2}$\) is the critical value for a given confidence level and SE is the standard error.

In this case,

\($\bar{x} = 30$, $z_{\alpha/2} = 1.96$ for 95% confidence level and SE = 1.33, so $$30 \pm 1.96 \times 1.33 = 30 \pm 2.61 = (27.39, 32.61)$$\)

This means that we are 95% confident that the true population mean of years worked by white collar criminals is between 27.39 and 32.61.

3. Calculate the 99% confidence interval using the same formula but with a different critical value:

\($$\bar{x} \pm z_{\alpha/2} \times SE$$ In this case, $z_{\alpha/2} = 2.58$\)

for 99% confidence level and everything else remains the same,

\(so $$30 \pm 2.58 \times 1.33 = 30 \pm 3.43 = (26.57, 33.43)$$\)

Therefore, by percentage the answer will be 26.57 and 33.43.
