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.

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”).

A large p-value means that there is a good chance that the relationship is statistically significant. If the two variables are not related in the population, then less than 5% of the samples you could ever take would give you a test statistic of 3.84 or larger. All of the above.

(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

(b) Find the P-value using Table C. Then obtain a more precise P-value from your calculator. 71. One-sided test Suppose you carry out a significance test of H0: μ = 5 versus Ha: μ < 5 based on a sample of size n = 20 and obtain t = −1.81. (a) Find the P-value for this test using Table C or technology.

This is used to generate critical values in the output and isn’t all that important as you will also be getting p-values with your output. The output looks like this. The mean, variance and number of observations are given for each group. The t-Stat is given. The p-values and …
