Question

47. Suppose you have a quantitative random sample: 47 48 63 58 54 59 49 51 47 51 and you wish to see if the population mean is significantly different than 50 (use this statement to construct your alternative hypothesis). Assume all appropriate assumptions are met. Calculate the p-value for the hypothesis test on the population mean. a) 0.002 < p-value < 0.01 b) 0.01 < p-value < 0.02 c) 0.02 < p-value < 0.05 d) 0.05 < p-value < 0.1 e) 0.1 < p-value < 0.2 Questions 48-49. A local banking company offers training classes for its associate analyst positions to each of its corporate employees. The class is mandatory for advancement, but space is limited in the class. The course is supposed to be equally available for employees of any race/ethnicity . About 20% of the employees are asians. Asians claim that they are not getting equal access to the associate analyst class and thus to further advancement (use this statement to construct your alternative hypothesis). Out of the past 100 students in the class, 17 of the students were asian. We are interested in seeing if there is statistically significant evidence of racial bias against asians in enrollment for the associate analyst class. 48. Compute the observed test statistic for the hypothesis test. a) 0.23 b) -0.8 c) 0.8 d) 0.75 e) -0.75 49. Compute the p-value for the hypothesis test. a) 0.2177 b) 0.2206 c) 0.2236 d) 0.2266 e) 0.2296 50. An article presents voltage measurements for a sample of 66 industrial networks in Estonia. Assume the rated voltage for these networks is 232V. The sample mean voltage was 231.5V with a standard deviation of 2.19V. Let ? represent the population mean voltage for these networks. Find the p-value for testing H0 : ? = 232 versus HA : ? ? 232. a) 0.0344 b) 0.0444 c) 0.0544 d) 0.0644 e) 0.0744
