Question

Use the GSS file to investigate whether or not Americans use the Internet at least 7 hours per week (estimating an hour per day). Perform the One Sample T Test procedure (as presented in SPSS Demonstration 1) to do this test with the variable WWWHR. Do the test at the.01 significance level. What did you find? Do Americans use the Internet 7 hours per week, more or less? One-Sample Statistics Mean Sad. Deviation Std. Error Mean W HOURS PER WEEK 540 11.97 15.568 670 One Sample Test Test Value o 95% Confidence Interval of the Difference Mean Uppe df Sig, (2-tailed) OWCT W HOURS PER WEEK 17.873 539 11,974 10.66 13.29 0

Explanation / Answer

p-value = 0.000   for two-tailed test
{see column Sig (2-tailed }

p-value for right-tailed test = 0.000 /2 = 0.000 {half of p-value of 2-tailed test}
alpha= 0.01
p-value < 0.01
hence
we reject the null hypothesis

we can conclude that Americans use the internet more than 7 hour per week
