A random and indepently chosen sample of four bags of marbles each labeled 20 pounds, had weights of 20.5, 19.8, 20.8, and 20.0 pounds. Assume that the distribution of weights in the population is normal and answer the following:
The null and alternate hypotheses is: H? : µ = 20; H? : µ > 20- (I think this is correct)
* Calculate the p-value using t-distribution (exact value): 0.1577 (What I calculated)
* Calculate the test statistic using the formula and make sure to show your work.
* Complete a decision regarding the null hypothesis, and write your conclusion about the original claim. Round all values to the nearest thousandth. Use a 5% level of significance for the decision
