= Homework: Homework #6 Given a normal distribution with = 100 and a = 10, complete parts (a) through (d). Click here to view page 1 of the cumulative standardized normal distribution table. Click here to view page 2 of the cumulative standardized normal distribution table. a. What is the probability that X>75? The probability that X>75 is 9938. (Round to four decimal places as needed.) b. What is the probability that X <90? The probability that X <90 is 0.1587. (Round to four decimal places as needed.) c. What is the probability that X<70 or X> 115? The probability that X<70 or X> 115 is .0682. (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 and less than (Round to two decimal places as needed.)

Given a normal distribution with u = 50 and 5, complete parts (a) through (d). Click here to view page 1 of the cumulative standardized normal distribution table. Click here to view page 2 of the cumulative standardized normal distribution table. a. What is the probability that X>44? P(X>44) 8849 (Round to four decimal places as needed.) b. What is the probability that X <45? P(X<45) 1587 (Round to four decimal places as needed.) c. For this distribution, 10% of the values are less than what X-value? X= 44 (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 and X- (Round to the nearest integer as needed.) BEES
