Now in the output below, we can see the results for the T-test. Look at the enlarged numbers under the column that says “t” for the t-value, “df” for the degrees of freedom, and “Sig. (2-tailed) for the p-value. (Notice that the p-value of .539 is greater than our “.05” alpha level, so we fail to reject the null hypothesis.

P-Value = 0.000. This tells us that the sample estimates of Pearson correlation of Day and Weight is -0.998 based on 14 observations. When test for significance, a low p-value rejects the null that rho=0 and we conclude that the sample estimates just did not come from the noise. There is a meaningful linear relationship between the two variables.

(i) Since this is an upper tailed test, reject H0 if t ( t(;n-1= t0.05;8 =1.86 or if the P-value=P(t>3.5764) is less than (=0.05. Notice that test statistics, 3.5764 is large than 1.86. (ii) 0.001

Three Ways to Find a P-Value from a t Statistic - Statology
Summary: To find the p-value for the hypothesis test for the difference in means, look in the column labeled “Sig. (2-tailed)” in the “t-test for Equality of Means” section, and in the second row (labeled “Equal variances not assumed”). Note that since the p-value given by SPSS is 2-tailed, you need to divide it in half for a 1-tailed test. In the above example the 1-tailed p-value would …
