What is the null and alternative hypothesis of the question below in symbols?

Question

Tom was testing whether 25 employees at a department store sell more shoes to customers if they had free coffee in the break room compared to the population of employees who sell an average of 22 shoes.

1. What is the null hypothesis in symbols? What is the alternative hypothesis in symbols? Show your reasoning after writing symbols.

Answer 1

Ho: population mean (mu) = 22

Ha: population mean (mu) > 22

this is a one-sided test as to whether free coffee breaks would increase the average number of shoes.
