Sleep (Raw Data, Software Required):
Assume the general population gets an average of 7 hours of sleep
per night. You randomly select 35 college students and survey them
on the number of hours of sleep they get per night. The data is
found in the table below. You claim that college students get less
sleep than the general population. That is, you claim the mean
number of hours of sleep for all college students is less than 7
hours. Test this claim at the 0.10 significance level.
(a) What type of test is this? This is a lefttailed test.This is a twotailed test. This is a righttailed test. (b) What is the test statistic? Round your answer to 2 decimal places. tx= (c) Use software to get the Pvalue of the test statistic. Round to 4 decimal places. Pvalue = (d) What is the conclusion regarding the null hypothesis? reject H_{0} fail to reject H_{0} (e) Choose the appropriate concluding statement. The data supports the claim that college students get less sleep than the general population. There is not enough data to support the claim that college students get less sleep than the general population. We reject the claim that college students get less sleep than the general population. We have proven that college students get less sleep than the general population. 
DATA ( n = 35 ) Sleep per Night College Students

A)
Less than means left tailed test
B)
Standard deviation of the given data = 1.5808
Mean = 6.5371
N = 35
Test statistics t = (observed mean  claimed mean)/(s.d/√n)
Observed mean = 6.5371
Claimed mean = 7
s.d = 1.5808
N = 35
t = 1.73
Degrees of freedom is equal to n1, 34
For df 34 and test statistics of 1.73
Pvalue is = 0.04635
As the obtained pvalue is less than the given significance level of 0.1
We reject Ho
The data supports the claim that students get less sleep than 7 hours
