Reject the null hypothesis.

There is enough evidence to claim that students study less than 150 minutes, on average, each week.

Step-by-step explanation:

Hello!

You have the Hypothesis that "students study less than 150 min, on average, per week"

Symbolically:

H₀:μ≥150

H₁:μ<150

α: 0.05

You have two ways of deciding whether to reject the null hypothesis or not.

With the calculated value: -2.68 (I'll assume this value was obtained under a standard normal distribution)

To take a decision using the statistic value you need to establish the critical region. For this Hypothesis pair, the rejection region is one-tailed to the left. The critical value is .

If the calculated value is less than -1.64, you reject the null Hypothesis.

If the calculated value is equal to or greater than -1.64, you support the null hypothesis.

Since the calculated statistic (-2.68) is less than -1.64, the decision is to reject the null hypothesis.

-or-

With the p-value 0.005

To take a decision using the p-value, you have to compare it against the significance level.

If the p-value is less than α, then you reject the null hypothesis.

If the p-value is equal or greater than α, you support the null hypothesis.

Since the given p-value is less than the significance level, you reject the null hypothesis.

I hope you have a SUPER day!
