38. Use the following information for questions 37-38: Suppose you conduct a hypothesis test to determine whether or not the average age difference between married couples is less than 5 years. You conduct this test at the 0.10 significance level and come to the conclusion that 0.01 < p-value < 0.02.

What is the appropriate conclusion?

	a.	The data does not provide statistically significant evidence that the average age difference of married couples is less than 5 years.
	b.	The data does not provide statistically significant evidence that the average age difference of married couples is 5 years.
	c.	The data does provide statistically significant evidence that the average age difference of married couples is 5 years.
	d.	The data does provide statistically significant evidence that the average age difference of married couples is less than 5 years.

Use the following information for questions 28-31: Suppose we run a model to determine the test score of a student based in their IQ and time spent studying. The model can be written as: Score = B0 + B1 IQ + B2 Sleep Hours + B3 Study Hours + e Where: Score = student's score on the test (out of 100) IQ = student's IQ score (representing intelligence in this model) SleepHours = number of hours slept the night before...

Please conduct a Hypothesis test in the following scenario to determine if the population slope is statistically significant. State the appropriate test statistic, the critical values, and whether or not you can reject a null hypothesis that the population slope is zero. Use a 1% significance level. Suppose that you collected data to determine the relationship between the amount of time a person spends online as an independent variable and the amount of money a person spends online as the...

Use the data from question 1. Conduct a hypothesis test at α = .01 to determine if the population variance is greater than 904.75. Question 1: 1. Consider the following sampled data: s 2 = 906.304, n = 31. Calculate the following confidence intervals for the population variance: (a) 90% (b) 95% (c) 99%

Suppose that we are to conduct the following hypothesis test: H0:μ =1030 H1:μ>1030 Suppose that you also know that σ=170, n=90, x¯=1058.9, and take α=0.01. Draw the sampling distribution, and use it to determine each of the following: A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a)(−∞,a) is expressed (-infty, a), an answer of the form (b,∞)(b,∞) is expressed (b, infty), and an answer...

Suppose that you wish to use a hypothesis test to test a claim made by a juice bottling company regarding the mean amount of juice in its 16 oz bottles. The company claims that the mean amount of juice in its 16 oz bottles is 16 oz, while you suspect the true mean is lower. You obtain n = 15 bottles of juice and find a sample mean of x¯ = 15.42 oz with a sample standard deviation of s...

Please use the p value approach to conduct a hypothesis test for the following problem. Please provide detailed solutions in the four steps to hypothesis testing. The security department of a factory wants to know whether the true average time required by night guard to walk his round is 30 minutes. If, in a random sample of 45 rounds, the night guard averaged 30.9 minutes with a`standard deviation of 1.8 minutes, determined whether this is sufficient evidence to reject the...
