Given a normal distribution with u= 53 and a= 3, 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> 487
P(X > 48) = 0.9522 (Round to four decimal places as needed.)
b. What is the probability that X< 47?
P(X <47) = 0.0228 (Round to four decimal places as needed.)
6. For this distribution, 9% of the values are less than what X-value?
X- 49 (Round to the nearest integer as needed.)
d. Between what two X-values (symmetrically distributed around the mean) are 60% of the values?
For this distribution, 60% of the values are between X= and X=
(Round to the nearest integer as needed.)
