gogolik [260]

Answer:

A. 0.0001

Step-by-step explanation:

z-statistic:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

The value of the z-statistic is z = 3.74.

The desired probability is 1 subtracted by the pvalue of z = 3.74.

z = 3.74 has a pvalue of 0.9999

Then

1 - 0.9999 = 0.0001.

So the correct answer is given by option A.
