Assume that the random variable X is normally​ distributed, with mean muequals45 and standard deviation sigmaequals10. Compute t
saul85 [17]

Answer:

0.1069 = 10.69%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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 pvalue, we get the probability that the value of the measure is greater than X.

In this question:

\mu = 45, \sigma = 10

Between 57 and 69

This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So

X = 69

Z = \frac{X - \mu}{\sigma}

Z = \frac{69 - 45}{10}

Z = 2.4

Z = 2.4 has a pvalue of 0.9918

X = 57

Z = \frac{X - \mu}{\sigma}

Z = \frac{57 - 45}{10}

Z = 1.2

Z = 1.2 has a pvalue of 0.8849

0.9918 - 0.8849 = 0.1069 = 10.69%
