- If X1 and X2 constitute a random sample of size n = 2from an exponential population, find the efficiency of 2Y1relative to X, where Y1 is the first order statistic and 2Y1and X are both unbiased estimators of the parameterDr. Ingrid is conducting an experiment to see whether time spent reading is related to poor vision. To do so, she creates three groups and randomly assigns 17 participants to each: the first group reads for 30 min a day, the second group reads for 1hr a day, and the third group reads for 1.5 hrs a day. Dr. Ingrid plans on using a one-way ANOVA to analyze the results of her experiment. If Dr. Ingrid has set alpha to .01, what will be her critical value of F?In a test of H0: µ=150 against HA: µ<150, a sample of size 250 produces Z = -0.65 for the value of the test statistic. Thus the p-value is approximately equal to
