Answer the following multiple choice questions:

A random sample of n = 120 people was sampled from a very large population. Each person was asked the question: "Do you think that taxes will be higher next year, as a result of the pandemic?" Fifty-six people responded "yes". a. What is the observed value of the discrepancy measure in order to test Ho: 0 = 0.5 (against the two-sided alternative hypothesis)? A) 56 B 4 C) 6 D) 7.2 E None of these b. Which of the following commands in R would be used to determine the exact p-value, based on the data, in order to test Ho: 0 = 0.50 (against the two-sided alternative hypothesis). A) 1 - pbinom (63,120,0.5) + pbinom(56,120,0.5) pbinom (56,120,0.5) + 1 - pbinom(64,120,0.5) C) pbinom (56,120,0.5) + pbinom(64,120,0.5) - 1 DJ 1 - pbinom (63,120,0.5) - pbinom(56,120,0.5) E) More than one of these is correct F) None of these are correctc. An approximate 95% confidence interval for the proportion in the study population that agreed with the statement is given by [0.377, 0.556]. According to Table 5.1 guidelines, how much evidence is there against Ho: 0 = 0.54 (against the two-sided alternative hypothesis), based on the observed data? A) There is no evidence against Ho. B) There is weak evidence against Ho. C) There is evidence against Ho. D) There is strong evidence against Ho. E) There is not enough information to assess the amount of evidence against Ho
