As part of your work for an environmental awareness group, you want to test the claim that the mean amount of municipal waste generated by adults in Switzerland is 1.7 kg (per day per person). You find that the mean municipal waste (per person per day) for a random sample of 13 adults in Switzerland is 1.93 kg, with a standard deviation of 0.4 kg. Can you conclude that the claim is untrue? Test at the 0.01 level of significance. Use this data for questions 13 to 18.

Choose the correct null and alternative hypotheses.

Group of answer choices

H0: = 1.7 kg; Ha: 1.7 kg

H0: 1.7 kg; Ha: = 1.7 kg

H0: = 1.7 kg; Ha: > 1.7 kg

H0: = 1.7 kg; Ha: < 1.7 kg

Flag question: Question 17

Decide whether or not we should reject the null hypothesis.

Group of answer choices

Since the test statistic falls in the rejection region, we fail to reject the null hypothesis.

Since the test statistic falls in the non-rejection region, we fail to reject the null hypothesis.

Flag question: Question 18

Interpret the results of the hypothesis test.

Group of answer choices

At the 1% significance level, the data does not provide sufficient evidence to conclude that the claim is untrue.
