An individual can take either a scenic route to work or a non-scenic route. She decides that use of the non-scenic route can be justified only if it reduces the mean travel time by more than 9 minutes. (a) If ?1 refers to the mean travel time for the non-scenic route and ?2 to the mean travel time for the scenic route, what hypotheses should be tested? ?1 − ?2 = −9 ?1 − ?2 < −9 ?1 − ?2 < −9 ?1 − ?2 > −9 ?1 − ?2 =−9 ?1 − ?2 ≠ −9 ?1 − ?2 = 9 ?1 − ?2 < 9 ?1 − ?2 = 9?1 − ?2 > 9 B) If ?1 refers to the mean travel time for the scenic route and ?2 to the mean travel time for the non-scenic route, what hypotheses should be tested? ?1 − ?2 = −9?1 − ?2 < −9 ?1 − ?2 = −9?1 − ?2 > −9 ?1 − ?2 = −9?1 − ?2 ≠ −9 ?1 − ?2 = 9?1 − ?2 < 9 ?1 − ?2 = 9?1 − ?2 > 9

Styles Font Paragraph Hypothesis Testing for College Tuition Cost D) Calculate the mean and standard deviation of your data set. You may use technology such as Google Sheets, Excel, or a TI-83/TI-84. Round to the nearest hundredth. In this assignment, you will be using inferential statistics to determine if a claim about college tuition cost is accurate. Standard Deviation According to the College Boarď's website, the average tuition cost per year for a public four- year college (in-state cost) is $10,230. Mean & A) Assume that you disagree with the claim. Do you think the average tuition cost is higher? Or lower? E) Using a significance level a = 0.05, find the critical value using the following steps. 1. What are the degrees of freedom? B) Using your answer in part A, write a set of hypotheses (null hypothesis and alternative hypothesis) to represent that claim and its complement. Replace the ?s below with the appropriate inequality signs (,2). Highlight the hypothesis that…

A baseball team claims that the mean length of its games is more than 1.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is not 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≥1.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.4." D. The null hypothesis expressed in words is, "the mean length of a…
