What are the appropriate null and alternative hypothe-ses to test whether the average full-service fee of US fu-neral homes this year is less than $7640?b. Conduct the test at a = .05. Do the sample data pro-vide sufficient evidence to conclude that the averagefee this year is lower than in 2019?c. In conducting the test, was it necessary to assume thatthe population of average full-service fees was normallydistributed? Justify your anSwer.419 words
