In standard lnornmal distribution, 1 constant value, is : (A) greater than P (Z 0 must be : (A) rejected. (B) accepted. (C) rejected or accepted based on the length of the 95%. (D) ignored, since there no association in between 95% and the hy- pothesis decision. Given two samples with sizes n = 27 and n2 = 41. To test on Ho: 1- 12 =0 vs H1: µ1-42 0, we need: 12 (A) to use z-statistic value, since n1 + na is large. (B) to use z-statistic value, since n2 is large enough to moderate vari- ation. (C) to use either z-statistic or t-statistic value, it is optional. (D) to use t-statistic value.

Question
-In standard normal distribution, P (|Z| < c), where c is any constant value, is : (A) greater than P (Z < c). (B) always less than P (Z < c). (C) always less than P(Z < c), but it can bosometimes greater. (D) no specific rule. In sample size determination, n 3= E2 doubling the standard deviation results in: (A) doubling the sample size. (B) quadrupling the sample size. (C) increasing sample size eight times. (D) No effect because E will increase. If 95% CI for pu1- p2 in two population means includes zero value, then H. in Ho : H1 - H2 = 0 vs H H1 - 12 > 0 must be : (A) rejected. (B) accepted. (C) rejected or accepted based on the length of the 95%. (D) ignored, since there no association in between 95% and the hy- pothesis decision. Given two samples with sizes ni = 27 and n2 = 41. To test on Ho: H-2 =0 vs H1 µ - 42 # 0, we need : 12 (A) to use z-statistic value, since n1 + n2 is large. (B) to use z-statistic value, since n2 is large enough to moderate vari- ation. (C) to use either z-statistic or t-statistic value, it is optional. (D) to use t-statistic value.
