For a random sample of 36 data pairs, the sample mean of the
differences was 0.71. The sample standard deviation of the
differences was 2. At the 5% level of significance, test the claim
that the population mean of the differences is different from
0.
What degrees of freedom are used?
Compute the t value. (Round your answer to
three decimal places.)
Estimate the P-value of the sample test
statistic.
P-value > 0.5000.250 < P-value <
0.500
0.100 < P-value < 0.250
0.050 < P-value < 0.100
0.010 < P-value < 0.050
P-value < 0.010
