'A normally distributed population has mean of 450 and standard deviation of 40_ Determine the probability that random sample of size 16 selected from this population will have sample mean less than 429. Determine the probability that random sample of size 25 selected from the population will have sample mean greater than or equal to 464. P(x <429) (Round to four decimal places as needed )'
