A normally distributed populntion has a mean of 600 ard a standard deriation of 36 . a. Determine the probability that a random sample of size 9 selected from this population will have a sampin mean less than 579 . b. Determine the probabilify that a random sample of size 16 selected from the population will have a sample mean greater than or equal to 623. a. P(x<679)= (Round to four decimal places as needed.) b. P(x≥623)= (Round to four decimal places as needed.)
