Question 5. Statistical inference for two Normal Populations with Known Variances For the test of the null hypothesis H,: H = Hz against the two-sided alternative H,: , # , two random samples with sizes n, = 1o and n = 10 from two independent normal populations are taken. The variances of the two populations are o, =7 and o, = 6, respectively. The sample means (X bar) were found to be 37-3 and 38.8 respectively. Find the observed value, zo, of the Z-statistic. Select one: a. None of the answers O b.-2.13 O c.1.95 O d.-1.31
