Would you favor spending more federal tax money on the arts? Of a random sample of n1 = 217 women, r1 = 68 responded yes. Another random sample of n2 = 189 men showed that r2 = 49 responded yes. Does this information indicate a difference (either way) between the population proportion of women and the population proportion of men who favor spending more federal tax dollars on the arts? Use α = 0.05. (a) What is the level of significance? What is the value of the sample test statistic? (Test the difference p1 − p2. Do not use rounded values. Round your final answer to two decimal places.) (c) Find (or estimate) the P-value. (Round your answer to four decimal places.)

Studies show that the level of anxiety has changed since the pandemic. The average score before the pandemic was mu equal to 36. A sample of 20 individuals surveyed in the past two weeks produced M=37.6 and s=9.8. Based on the sample, was there a significant difference in the average anxiety level since the pandemic started at the 5% significance level? What is the positive critical value? (a)2.093 (b)2.086 (c)1.729 (d)1.725
For this study, we should use The null and alternative hypotheses would be: z-test for a population proportion or t-test for a population mean Ho: (p or u) (please enter a decimal) H1: (p or u) (Please enter a decimal) The test statistic z = (please show your answer to 3 decimal places.) The critical value = (Please show your answer to 3 decimal places.) The test statistic (is or is not) in the rejection region. Based on this, we should (reject or accept or fail to accept) the null hypothesis. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly larger 50% at � = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is larger 50%.
