Using the t-distribution, it is found that there is not enough evidence that the diet is helping people lose weight.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the mean hasn't decreased, that is:

.
.
Hence, for the distribution of differences, they are:
.
<h3>What is the test statistic and the decision?</h3>
The test statistic is:

In which
is the value tested at the null hypothesis.
Hence:


t = 0.85.
Considering a right-tailed test with 9 + 9 - 2 = 16 df, with a standard significance level of 0.05, the critical value is t = 1.7459. Since t = 0.85 < 0.85, there is not enough evidence that the diet is helping people lose weight.
