A survey asks "would you like to see more or less government spending on natural disasters?" Of the 1496 respondents, 723 responded "more" or "much more". The proportion of respondents who responded "more" or "much more" is an example of Select one: O A. a parameter O B. the population O C. random sampling O D. the sample O E. a statistic Clear my choiceState conclusion to significance test in terms of the null hypothesis In a random sample of 88 adults from a particular town, it is found that 6 of them have been exposed to a certain flu strain. At the 0.01 significance level, test the claim that the proportion of all adults in the town that have been exposed to this flu strain differs from the nationwide percentage of 8%. Ho: p = 0.08 Ha: p # 0.08. a = 0.01 Test statistic: z = -0.41. P-Value = 0.6828 State your conclusion in terms of Ho. Select one: O A. Do not reject Ha since the P-value is larger than a. O B. Do not reject Ho since the P-value is larger than a. O C. Reject Ho since the P-value is larger than a. O D. Reject Ha since the P-value is larger than a. O E. Since the P-value is larger than a, we conclude that the proportion of adults in this particular town that have been exposed to this flu strain differs from the nationwide percentage of 8%.Suppose the following tree diagram summarizes the responses of 500 people to two questions, where the first response is either yes or no and the second is multiple choice with three possible answers (A, B or C). Use the tree diagram to calculate the probability that a person answered B to the multiple choice question. A (0.1) Y (0.1) B (0.4) C (0.5) A (0.2) N (0.9) B (0.3) C (0.5) Select one: E. O.7 O A. 0.04 O B. 0.4 O C. 0.31 OD. 0.07Select the most appropriate answer. For two events A and B, P(A) = 0.4, P(B) = 0.3, and P(A and B) = 0. It follows that A and B are Select one: O A. complementary. O B. both disjoint and independent. O C. disjoint but not independent. O D. independent but not disjoint. O E. neither disjoint nor independent
