Question: Test the hypothesis that there has been a weight loss between the start of the program and the 3-month follow up screening with a confidence level of 95%.

a) State the null and alternative hypotheses for the test about to be performed.
b) Open the Analysis, ANOVA, and then One-Way ANOVA menu. Select paired sample. Then move to the data window. Move Weight and Weight3 to the analysis variable task role. Select Analysis and leave the null hypotheses value equal to 0. Leave the equal tailed box checked and the confidence level at 95%. Move to the plots menu and select summary, histogram, box plot, and normal quartile-quartile (Q-Q) plot. On the title menu, unclick the default title and manually type T-test of a Single Sample. Click run.

c) Review the summary statistics, box plot, Q-Q plot and histograms. Do the required assumptions for the t-test appear to be met?

d) From the t-test output, determine what decision to make regarding the null hypotheses and explain your rational. If you reject the null, what are the 95% confidence limits for the actual weight loss over the three month period?

e) Copy what you consider to be the relevant output to your assignment document and include a detailed written analysis of your results.
