A consumer advocacy group suspects that a local supermarket's 10-ounce packagesof cheddar cheese actually weigh less than 10 ounces. The group took a randomsample of 50 such packages and found that the mean weight for the sample was9.955 ounces. The population follows a normal distribution with the populationstandard deviation of .15 ounce.Discuss the question: Is there a statistically significant difference in the meanweights of 10-ounce packages in the sample compared to the labeled amount of 10-ounces?Include the following points in your discussion:1. What does "statistical significance" mean in relation to this question2. Why isn't it enough to say that "since the mean weight in the sample is lessthan 10 ounces, it is clear that the labelling is incorrect"?3. Construct a hypothesis test for this question4. Perform the hypothesis test analysis for a significance level of 1% using thecritical-value approach (Test Statistic comparison)5. What is the p-value for this test? Will you reject the null hypothesis at ?

We have given that Sample size n = 50 Sample mean = 9.955 Standard deviation = 1.5
