Hugo averages 58 words per minute on a typing test with a standard deviation of 11 words per minute. Suppose Hugo's words per mi
Black_prince [1.1K]

Answer:

The number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his mean (58)

Step-by-step explanation:

A normal random variable with mean Mu = 58 and standard deviation sd = 11 is standardized with the transformation (z-score):

Z = (X - Mu) / sd = (X - 58) / 11

For a value of 74 for X, Z = (74 - 58) / 11 = 1.4545 > 0.

The z-score when X = 74 is 1.4545 > 0

This means that the number of words that Hugo wrote in the test of Wednesday (74) is at a distance of 1.4545 standard deviations (11) to the right of his average (58)
