如題:型二誤差不會算，請各位大大拔刀相助~~1.我理解力弱，希望可以講淺顯一點~~下面題目雖有答案但看唔A researcher wants to study the average lifetime of a certain brand of light bulbs (in hours). In testing the hypotheses, H0: m = 950 hours vs. H1: m 1 950 hours, a random sample of 25 light bulbs is drawn from a normal population whose standard deviation is... 顯示更多 如題:型二誤差不會算，請各位大大拔刀相助~~ 1.我理解力弱，希望可以講淺顯一點~~下面題目雖有答案但看唔 A researcher wants to study the average lifetime of a certain brand of light bulbs (in hours). In testing the hypotheses, H0: m = 950 hours vs. H1: m 1 950 hours, a random sample of 25 light bulbs is drawn from a normal population whose standard deviation is 200 hours.(a) Calculate b, the probability of a Type II error when m = 1000 and a = 0.10. ANS: b = P(884.2
