Question 22 4 pts The number of patients admitted per day to a large hospital's ICU follows a skewed right distribution with a mean of 20 and a standard deviation of 8. Suppose a sample of 100 days was collected over the past year and the average number of patients admitted per day was calculated. Does the Central Limit Theorem apply to this problem? No Yes, since np and nq are both at least 15 Yes, since n is at...
