Question 16 Not yet answered Points out of 5.00 Flag question Consider again the random sample of n = 100 Super-Modified Widgets, purchased by customers, that have been selected to have their lifetimes carefully monitored. What is the probability that the lifetimes of no more than half (i.e., 50) of the widgets in the sample exceed the population mean lifetime that has been determined by the engineers? Use the Normal approximation to the Binomial distribution to approximate this probability. For the Binomial probability, P, use a value rounded to four decimal places. Rounding Instructions: Use maximum precision in all intermediate calculations. In using the standard normal table to look up the probability, before doing the look-up round the z-value to 2 decimal places to match the precision of the z-values in the table. Finally, round the resulting probability itself to 5 decimal places, consistent with the probabilities given in the table. EN English (United States)
