Let p denote the population proportion of all buttered toast that will land with the buttered side down when dropped. Identify the null and alternative hypotheses to test the claim that buttered toast will land with the buttered side down 50% of the time. Ho p = H₁p 0.5 0.5 (Type integers or decimals. Do not round.) Identify the test statistic. z = -1.81 (Round to two decimal places as needed.) Identify the P-value. P-value = 0.070 (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that buttered toast will land with the buttered side down 50% of the time. Write a conclusion that addresses the test that the toast will land with the buttered side down more than 50% of the time. The intent of the experiment was to test Ho: p = down more than 50% of the time. 0.5 and H₁: p > 0.5.…
Researchers conducted a study to determine whether magnets are effective in treating back pain. The results are shown in the table for the treatment (with magnets) group and the sham(or placebo) group. The results are a measure of reduction in back pain. Assume that the two samples are independent simple random samples selected from normally distributedpopulations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05significance level for both parts. a. Test the claim that the two samples are from populations with the same mean. What are the null and alternative hypotheses? What is the test statistic, t? What is the P-value? State the conclusion for the test. b. Construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean.

Do men have a higher body temperature than women? Test the indicated claim about the means of two populations. Assume that the two samples are randomly selected, independent, the population standard deviations are not know and not considered equal. The table shows results from a study of body temperatures of men and women. At the 0.05 significance level, test the claim that men have a higher body temperature than women.
