al The number of hours spent watching Netflix by students in the week before their final exams has a normal distribution with a standard deviation of 5 hours. A random sample of 28 students was taken. be ma um ns mm a is the probability more than 0.9 that the sample standard deviation exceeds 4 hours? b. is the probability more than 0.975 that the sample standard deviation is less than 6.5 hours? Click the icon to view a table of lower critical values for the chi-square distribution Click the icon to view a table of upper critical values for the chi-square distribution. XX a. Select the correct choice below and fill in the answer boxes to complete your choice (Type integers or decimals. Use ascending order.) CA No, the probability that the sample standard deviation exceeds 4 hours is not more than 0.9 because it lies between and ✔ Yes, the probability that the sample standard deviation exceeds 4 hours is more than 0.9 because it lies between 0.9 and 0.95 b. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Use ascending order.) OA. No, the probability that the sample standard deviation is less than 6.5 hours is not more than 0.975 because it lies between and OB. Yes, the probability that the sample standard deviation is less than 6,5 hours is more than 0.975 because it lies between and
