Using the normal distribution, the probability that x is less than 110 is:
A. 0.975.
<h3>Normal Probability Distribution</h3>The z-score of a measure X of a normally distributed variable with mean and standard deviation
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given as follows:
The probability is the <u>p-value of Z when X = 110</u>, hence:
Z = 2
Z = 2 has a p-value of 0.975.
Hence option A is correct.
