Sleep TimeA person read that the average number of hours an adult sleeps on Friday night to Saturday morning was7.3 hours.The researcher feels that college students sleep more than7.3hours on average. The researcher randomly selected16 students and found that on average they slept8.3hours.The standard deviation of the sample is1.1

hours.At= 0.05,is there enough evidence to say that college students sleep more than7.3

hours on average? Assume that the population is approximately normally distributed. Use the critical value method and tables.

Part 1 of 5

(a) State the hypotheses and identify theclaim.:

H0: _________________ Choose one: claim or not to claim

H1:____________________ Choose one: claim or not to claim

This hypothesis test is a __________________ test. Choose one: one-tail or two-tail

(b) Find the critical value(s). Round the answer(s) to three decimal places. If there is more than one critical value, separate them with commas.

Critical value(s):

(c) Compute the testvalue.Always roundt score values to three decimal places.

t=

(d) Make thedecision. Pick one

reject /do not reject the nullhypothesis.

(e) Summarize theresults.

There is________________that college students sleep more than7.3 hours on average.

a) enough evidence to support the claim
