Consider the information above and in question 1. It is conjectured that the mean number of people attending all 2017 Veterans Day celebrations is 145, and of interest is to test this conjecture versus the alternative that the mean number of people attending all 2017 Veterans Day celebrations is different from 145 people To test the hypothesis, a simple random sample of 41 Veterans Day celebrations was selected and the number of people attending each was recorded. The mean number of people attending for this sample of 41 celebrations was 157, with a standard deviation of 23 people. The distribution of the data was bimodal. If appropriate, use this information to test the hypotheses stated in question 3 at the a = .05 level of significance. What is the correct value of the test statistic? A) z=3.34 B) z=2.74 C) z = 1.879 D) t=3.341 E) t=-3.417 F) z = 1.88 G) z=-3.341 H) t = 1.879 I) z=-3.417 J) t=2.741 K) z=-3.42 L) t=3.3 M) t = -1.879 N) t=-3.42
