Answer:
0.4532
Step-by-step explanation:
Given the question :
Find the percentage of area under a normal curve between the mean and the given number of standard deviations from the mean.1.68
Number of standard deviations from the mean = 1.68
I. 68 standard deviations below the mean :
Mean = 0(normal distribution)
P(Z < 0) = 0.5
1.68 standard deviations above the mean = + 1.68
P(Z < 1.68) = 0.95352
P(0 < x < Z) = (0.95352 - 0.5) = 0.4532
