Using the normal distribution, it is found that the value of x is of 3.585.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

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

  • It 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, which is the percentile of X

In this problem, the mean and the standard deviation are given, respectively, by \mu = 2.5, \sigma = 0.5.

The value of x is the 100 - 1.5 = 98.5th percentile, which is X when Z = 2.17, hence:

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

2.17 = \frac{X - 2.5}{0.5}

X - 2.5 = 0.5(2.17)

X = 3.585

Hence the value of x is of 3.585.
