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...

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean mu equals 281 days μ=281 days and standard deviation sigma equals 28 days. (b) Suppose a random sample of 21 pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies. The sampling distribution of x is _____ (skewed left, skewed right, normal) with u-x = _____ and o-x= _____. (Round to 4 decimal places as needed)
