Find the p-value in a test of the claim that the mean College Algebra final exam score of engineering majors equal to 88, give
n that the test statistic is zequals1.50.
1 answer:
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.

The numerical values of the mean and standard deviation are 4 and 1.55, respectively
<h3>The numerical value of the probability that x = 6. </h3>The given parameters are:
n = 10
π = 0.4
The probability is then calculated as:
So, we have:
Apply the combination formula
So, we have:
Evaluate
P(6) = 0.1115
Hence, the numerical value of the probability that x = 6 is 0.1115
