A random sample of 100 households and collect data on eachhousehold’s income. You find a sample income standard deviation of$160,000. You want to test the null hypothesis that the populationmean income is $100,000, using a p-value of 0.05, against thealternative that it does not equal $100,000.
You will:
A. Reject the null hypothesis if the sample mean is $130,000
B. Fail to reject the null hypothesis if the sample mean isbetween $80,000 and $120,000
C. Fail to reject the null hypothesis if the sample mean is lessthan $120,000
D. Accept the null hypothesis
