Question

Hello, please answer with either formula or preferably with TI-84 ONLY. (No r studio, etc) thanks!

For problems #13 to #18, test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, then state the conclusion about the null hypothesis, and final conclusion that addresses the original claim.If you are using graphing calculators, show all commands.

14. A sample of 62 households was taken to measure the amount of discarded plastics. The sample mean was 1.911 lbsand the standard deviation was 1.065 lbs. Test the hypothesis that the amount of discarded plastics per household was 1.800 lbs. Use a 0.05 significance level.

??:

??:

Test Statistic:

P-value =

Reject ??. OR Fail to reject ??. (Circle one)

Final Conclusion:

Answer 1

STAT --> TESTS --> T test --> Stats

H0 : ? =1.800

H1 : ? ≠1.800

Test Statistic: 0.821

P-value = 0.4150

Fail to reject ??. (Since P-value >0.05)

Final Conclusion: There is not sufficient evidence to warrant rejection of the claim that amount of discarded plastics per household was 1.800 lbs.
