Given a normal distribution with mu equals 100 and sigma equals 10 comma complete parts (a) through (d). cumulative standardized normal distribution table.
a. What is the probability that Upper X greater than 80?
The probability that Upper X greater than 80 is . (Round to four decimal places as needed.)
b. What is the probability that Upper X less than 95?
The probability that Upper X less than 95 is . (Round to four decimal places as needed.)
c. What is the probability that Upper X less than 85 or Upper X greater than 110?
The probability that Upper X less than 85 or Upper X greater than 110 is . (Round to four decimal places as needed.)
d. 80% of the values are between what two X-values (symmetrically distributed around the mean)?
80% of the values are greater than nothing and less than . (Round to two decimal places as needed.)
