1)

• I claim that the mean weights of rocks on the beach is 7 ounces.


• The mean weight of a sample is 5 ounces.


• P-value = 0.03


• Confidence level (alpha) = 0.05

State the null and alternative hypotheses. Interpret the results. Explain your answer.

2)

• I claim that the mean weights of rocks on the mountain is 15 pounds.


• The mean weight of a sample is 16 pounds


• P-value = 0.3


• Confidence level (alpha) = 0.01

State the null and alternative hypotheses. Interpret the results. Explain your answer.
