butalik [34]

The appropriate conclusion of the hypothesis is; The researcher has statistical evidence to conclude that the population mean shower length for high school students is greater than 10 minutes.

<h3>What is the conclusion of the hypothesis?</h3>

We are given;

Sample size; n = 125

Population mean; μ = 10 minutes

Sample Mean; x' = 14.7 minutes

Now, we are told that the hypothesis was carried out and the p-value was 0. Now, the significance level is  α = 0. 05 and this means that the p-value is less than the significance level.

In conclusion, we will reject the null hypothesis and conclude that there is sufficient evidence to conclude that the population mean shower length for high school students is greater than 10 minutes.

+1 or -1 both possible --> solve both

+1+w=3 --> w = 3 - 1 = 2

OR

-1+w=3 --> w = 3 + 1 = 4
