What is a p-value and how is it used to make a decision about the null hypothesis?
How is the p-value related to the test statistic?
Explain whether or not rejecting the null hypothesis makes the alternative hypothesis true and why.
If I conduct a hypothesis testing with Type I error set at 0.05 and a resulting p-value of 0.3, what would my conclusion be?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses both the claim and the significance level alpha. Use the P-value method. A sample of 17 jellybeans with a mean weight of 0.8295 g was taken. Assume that σ is known to be 0.0565 g. Consider a hypothesis test that uses a 0.05 significance level to test the claim that the mean weight of all jellybeans is equal to 0.8550 g...
