Answer: 0.9332.

Step-by-step explanation:

Claim : College Algebra final exam score of engineering majors equal to 88.

Given that : The test statistic is z equals to 1.50.

To find the p-value (Probability value), we use standard normal distribution table, and search the p-value corresponds to the z-score.

In a Standard Normal Distribution Table below, the p-value corresponds z equals 1.5 is 0.9332.

Hence, the p-value is 0.9332.
