Consider the following hypothesis test: Claim: σ > 6.6 Sample Size: n = 9 Significance Level: α = 0.025 Enter the smallest critical value. (Round your answer to nearest thousandth.)
The table below shows the weights of seven subjects before and after following a particular diet for two months.
Subject / A / B / C / D / E / F / G
Before / 151 / 152 / 150 / 153 / 151 / 152 / 153
After / 153 / 155 / 153 / 150 / 150 / 152 / 153
Using a 0.025 level of significance, test the claim that the diet is effective in reducing weight (after minus before is negative). Use the p-value method of hypothesis testing.
Enter the p-value. (Round your answer to nearest thousandth.)
