A newspaper article headline claims that bystanders perform CPR correctly 43% of cases where needed. A healthcare professional believes the percentage is higher. She cites a study of 880 cases in which 396 bystanders performed CPR correctly. Test this hypothesis at the 0.01 significance level. Round-off your answers correct to 2 decimal places. a) Find the critical value(s). If there are two values (2 -tail test), type the negative value first and separate them with a comma. b) Calculate the test statistic c) Make a decision. Type R if you choose to "Reject the null hypothesis" Type F if you choose to "Fail to reject the null hypothesis.

They ask 16 ppl to take the SAT while wearing their best professional outfit. 6 months later they have the same 16 ppl take the SAT while wearing a bathing suit. What test would you use and why?

A sociologist believed that the average family size in Saskatchewan was larger than the average family size in British Columbia. Random samples from the two provinces yielded the following results: s? Saskatchewan (Pop 1) British Columbia (Pop 2) 3.45 1.34 60 2.89 1.32 52 Test at a = 0.05 whether there is sufficient evidence to support the claim. As well, calculate the p-value for this test.

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1413 referee calls, with the result that 426 of the calls were overturned. Women challenged 742 referee calls, and 228 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Identify the test statistic. z= ? (Round to two decimal places as needed.) Part 3 Identify the P-value. P-value= ? (Round to three decimal places as needed.) Part 4 What is the conclusion based on the hypothesis test? The P-value is ▼ greater than or less than the significance level of α=0.05, so ▼ fail to reject or reject the null hypothesis. There ▼ is not sufficient or is sufficient evidence to warrant rejection of the claim that women and men have equal success in challenging calls. Part 5 b. Test the claim by constructing an appropriate confidence interval. The 95% confidence…
A researcher believes that low BMI levels are indicators of eating disorders. He collects BMI of a sample of young adults identified as at risk for eating disorfers to see if their mean BMI is significantly below 18.5 What test would you use and why? (z test, independent t test, single sample t test, paired samples)
According to a survey conducted by the Association for Dressing and Sauces, 85% of American adults eat salad at least once a week. A nutritionist suspect that the percentage is higher that this. She conducts a survey of 200 American adults an finds that 171 of them eat salad at least once a week. Conduct the appropriate test that addresses the nutritionist's suspicions. Use the a = 0.1 level of significance. What is the test statistic? t-score population parameter Z-Score standard deviation
Data from 500 random tornados was collected and the length in miles that the tornado was touching the ground was recorded. We want to test the claim that the mean tornado length is greater than 2.5 miles using a .05 significance level. Using the traditional method if the test statictic is .759, x hat = 2.72424 and s= .2956. Tell why you made the decision you did.

Round your answer to three decimal places.
A random sample of size 21 was taken from a normal population. The sample average was 9.87 and the sample SD was 1.17. At the significance level of 10%, what test should you use for testing whether the population mean equals 9.7? One sample z-test for the population mean. two sample z-test for the population means. One sample z-test for proportions. two sample z-test for proportions. one sample t-test for the population mean. 3 26
