A diet center claims that it has the most effective weight loss program in the region. Its advertisements say, 'Participants in our program lose more than 7 pounds within a month'. A sample of 10 clients of this program are weighed on the first day of the diet and then one month later.

1. What is the p-value of the test (round to 4 decimal places)?

P-value = 0.3334

Step-by-step explanation:

We have a hypothesis test, with this null and alternative hypothesis:

(The null hypothesis states that the weight loss is equal or higher than 7)

The significance level is assumed as 0.05.

From the table, we have a sample mean of 2.1 and a sample standard deviation of 34.7.

The t-statistic is

For 9 degrees of freedom, the P-value for t=-0.445 is P(t<-0.445)=0.3334.

This P-value is bigger than the significance level, so the effect is not significant. The null hypothesis is not rejected.
