Question

Suppose a company sells bacon in packages that they claim average a weight of 14 ounces. Timothy believes that the actual average weight of the packages is different than what the company claims, and would like to test this using a significance level of 0.05. He takes a random sample of 51 packages and gets a sample mean of 14.42 ounces and a sample standard deviation of 1.08 ounces. (a) What are the null and alternative hypotheses? H?: p < 14 HA: p = 14 (b) What is the test statistic? (Round your answer to 3 decimal places, if needed.) (c) Using the statistical table, the p-value is 0.01 < p-value < 0.02 (d) Based on the p-value, Timothy should reject the null hypothesis. (e) This data provides sufficient evidence to conclude that the actual average weight of the packages is less than what the company claims. Check
