Click here to view page 2 of the cumulative standardized normal distribution table. a. What is the probability that X > 42? P(X > 42) = 0.9525 (Round to four decimal places as needed.) b. What is the probability that X< 44? P(X< 44) = .1587 (Round to four decimal places as needed.) c. For this distribution, 6% of the values are less than what X-value? X= 42 (Round to the nearest integer as needed.) d. Between what two X-values (symmetrically distributed around the mean) are 80% of the values? For this distribution, 80% of the values are between X=O and X= (Round to the nearest integer as needed.)
