To identify the correct Z(critical), it is important to determine whether the hypothesis test is one-tailed or two-tailed. The decision between a one- andtwo-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected.Many people believe that millennials are having more sex than people during the sexual revolution. You wonder whether the cohort currently in theirtwenties had sex at an earlier age than older generations. Assume that the the average age of first sexual intercourse is 17.4 years. You obtain asample that yields a sample mean of X = 15.9 years.Let u denote the average age of first sexual intercourse. Formulate your null and research hypotheses by selecting the appropriate values in thedropdown menus that follow.Ho:(H₁:The test you conduct istest.Note: A one-tailed test is described as a lower-tailed test if the null hypothesis is rejected for values of the test statistic in the lower tail of its distribution, and it is described as anupper-tailed test if the null hypothesis is rejected for values of the test statistic in the upper tail of its distribution.

The hypothesized mean is 17.4 years.

I was interested in how many days a week people do laundry. I asked 11 of my coworkers and friends how many days a week they do laundry and got the following data: 1,2,4,1,1,7,1,3,3,2,2. I was surprised that someone does laundry EVERY day! I believe the population mean of how many days a week people do laundry is less than 3 days. I tested this hypothesis at the .06 significance level. Assume a random sample.
Any basketball fan knows that Shaquille O'Neal, one of the NBA's most dominant centers of the last twenty years, always had difficulty shooting free throws. Over the course of his career, his overall made free-throw percentage was 53.3%. During one offseason, Shaq had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shaq made 26 of 39 free-throw attempts. Test the claim at the 0.05 SL that Shaq has significantly improved his free-throw shooting. What is the test statistic z? Round to 2 decimal places.

In the NFL, Coaches can throw "challenge" flags if they believe officials have made an incorrect call on the field. Then, based upon further analysis, the call is either overturned (because the referees were incorrect) or upheld (referees were correct). In the first eight weeks of last NFL season, there were 316 challenges made, with 154 of those calls overturned. The NFL team owners used this data to begin a lawsuit that claimed referees were wrong more than 50% of the time in challenged situations. They want to perform statistical analysis before filing that lawsuit. For the following question, select the answer which correctly responds. Using the analysis presented in previous questions about this claim, is the NFL owners' complaint merited? That is, should they proceed in filing the lawsuit? O Yes O No

A homeopathic drug company developed a new drug designed to prevent colds. The company claims there is no difference between the effectiveness for men and women. To test the claim they chose a simple random sample of 100 women and 150 men who participated in the trial.At the end of the study, 56% of the women caught a cold, and 40% of the men caught a cold. Based on these findings we are testing to see if there is a difference in the effectiveness for women and men.a) Define the parameter(s) of interest.b) State the Hypotheses.c) Find the value of the relevant sample statistic using correct notation:_________________________ Based on the randomization distribution below, what is the p-value ____________________

Destiny wants to know whether gender predicts depressive symptoms in patients with heart disease. She assesses the number of depressive symptoms experienced by a large sample of patients and finds that the data on depressive symptoms are positively skewed. Which assumption of a single-sample z test has Destiny most likely violated?
Using the latest in medical technology, an orthopedic doctor has developed a new surgical procedure that he believes is an improvement over the standard procedure. He wants to study whether the mean recovery time of patients who have the new procedure is less than the mean recovery time of patients who have the standard procedure. The doctor studies a random sample of 11 patients who have the new procedure and a random sample of 10 patients who have the standard procedure. (These samples are chosen independently.) The doctor records each patient's recovery time (in days). These data are shown in the table. Recovery times (in days) 350, 284, 291, 393, 295, 377, 401, 371, 423, 449, 364 New procedure Standard procedure 435, 409, 419, 423, 388, 410, 412, 438, 396, 424 Send data to calculator Send data to Excel Assume that the two populations of recovery times are approximately normally distributed. Can the doctor conclude, at the 0.01 level of significance, that the population mean of the…
A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?
A group of statisticians decides they will answer the question: Has the wolf reintroduction to Yellowstone been detrimental to elk herds in the park? They decide that each of the four data scientists will take a quadrant of the park to collect a sample from as randomly as possible. They decide they will collect the sample during the winter, the time the elk herds are most stressed. They agree to trust each others professional judgement when it comes to the health of the individual elk in the herd. They will give each elk a grade out of 3pts: 1 pt for sick, 2pts for fair, and 3pts for healthy. They then share their data and compare to create a final report on the overall health of the elk in the park. In this scenario, what is the same for all samples (the control)?
