Chapter 7 Homework Assignment
Using the following uniform density curve, answer the question.
Px)
125-
1) What is the probability that the random variable has a value greater than 5?
2) What is the probability that the random variable has a value less than 6?
Provide an appropriate response.
3) Find the area under the standard normal curve to the left of z = 1.5.
4) Find the area under the standard normal curve to the right of z = -1.25.
5) Find the area under the standard normal curve between z = -1.5 and z = 2.5.
Find the indicated z-score.
6) Find the z-score for which the area under the standard normal curve to its left is 0.96
7) Find the z-score for which the area under the standard normal curve to its right is 0.07.
8) Find the z-score having area 0.86 to its right under the standard normal curve that is, find z086
Find the indicated value.
9) za.005
10) z0 36
Provide an appropriate response.
11) Find the indicated 1Q score. The graph depicts I0 scores of adults, and those scores are normally distributed
with a mean of 100 and a standard deviation of 15 (as on the Wechsler test).
The shaded area under the curve is 0.10.
Assume that X has a normal distribution, and find the indicated probability.
12) The mean is u= 60.0 and the standard deviation is o = 4.0.
Find the probability that X is less than 53.0.
