Question

im stucked on this question. please help me solve it thanks

The same week her colleague selects a random sample of the nearby McDonalds customers and records their spending.

A. Conduct hypothesis test and determine the p-value. Enter the p-value below.

For this question only, you can assume the population standard deviation is $10.

B. Determine the critical value used when testing the hypothesis that McDonalds customers spend less than the national average at the 10% level of significance.

For this question only, you can assume the population standard deviation is known.

C. If we wished to create a confidence interval for the true mean customer spend for the specialty coffee shop that has a sampling error of $1.50 at the 10% significance level, what sample size should we use?

For this question only, assume the specialty coffee shop population variance is exactly equal to that of your sample.
