Determine the null and alternative hypotheses for theproposed hypothesis test.A researcher is interested in comparing the resting pulserate of women who exercise regularly and women whodo not exercise regularly. She wants to perform ahypothesis test to determine whether the mean restingpulse rate of women who exercise at least 6 hours perweek is less than the mean resting pulse rate of womenwho exercise less than 6 hours per week.O Let u, denote the mean resting pulse rate for women whoexercise at least 6 hours per week and let denote theH₂mean resting pulse rate for women who exercise less than 6hours per week.

Find the P -value for the indicated hypothesis test. A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 120 of the school's students, 30% of them plan to go into general practice. Find the P -value for a test of the school's claim.
A university offers a certain course that students can take in-person or in an online setting. Teachers of the course were curious if there was a difference in the passing rate between two settings. The teachers selected random samples of 200 students who take the course in-person and 300 students who take the course online for the hypothesis testing. From these two independent samples, 80% of the students passed the in-person setting and 75% of students passed the online setting. They were willing to treat these as representative samples ofall students who may take each setting of the course. (a) Test whether there is a difference in the passing rate between two course settings at 4% significant level. (b) Find the p-value of the test and does it lead to the same conclusion in (a)? (c) Find the 96% confidence interval to estimate the difference between the proportion of students who pass in each setting of the course (Pin-p 'in-person – Ponline).
When conducting a hypothesis test, we hope to avoid commiting a type 1 error, which is: 1. Not as bad as committing a type 2 error 2. rejecting a null hypothesis when it is true 3. rejecting the alternate hypothesis when it is true 4. accepting the null hypothesis when the alternate hypothesis is true
The mayor of a town believes that over 70% of the residents favor annexation of an adjoining community. Is there sufficient evidence at the 0.05 level to support the mayor's claim? After information is gathered from 130 voters and a hypothesis test is completed, the mayor decides to reject the null hypothesis at the 0.05 level. What is the conclusion regarding the mayor's claim?
A random sample of upperclassmen (juniors, seniors) and a random sample of lowerclassmen (freshman, sophomores) were asked if they use study groups for any of their classes. 157 (63%) out of 250 upperclassmen and 232 (58%) out of 400 lowerclassmen reported using study groups. Suppose all the assumptions for conducting the hypothesis test are met.
What does the decision to retain null hypothesis implies?
Describe the significance of null hypothesis.

A group of 250 patients was randomly split into two groups of 125 patients. The first group of 125 patients was given treatment A, and 72 of them improved their condition. The second group of 125 patients was given treatment B, and 60 of them improved their condition. Perform a hypothesis test to investigate whether there is evidence of a difference between the two treatments. What is the p-value of the test?
A researcher would like to test the claim that the proportion of middle-aged smokers with a lung capacity under 3 liters is less than the proportion of senior citizen nonsmokers with a lung capacity under 3 liters. A random sample of 46 middle-aged smokers had 32 with lung capacities under 3 liters, and a random sample of 46 senior citizen nonsmokers had 25 with lung capacities under 3 liters. These two independent samples will be used in a hypothesis test of this claim. Which test statistic formula should be used for this test?

A recent Food and Drug Administration (FDA) report states that 65% of all domestically produced food products are pesticide free. Suppose an FDA spokesperson believes that less than 65% of all foreign produced food products are pesticide free.

According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value
