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 / 152 / 152 / 152 / 150 / 152 / 151 / 150 After / 151 / 151 / 152 / 151 / 152 / 153 / 155 

Using a 0.05 level of significance, test the claim that the diet is not effective in reducing weight (after minus before is not negative). Use the p-value method of hypothesis testing.

Enter the test statistic. (Round your answer to nearest hundredth.)
