# Test of hypothesis

Candies manufactured by Cherrie Chocolate Candies Co, are supposed to weigh at least 2.00 ounces. A sample of 100 candies yields the following results.
Sample mean: 1.98 ounces
Sample standard deviation: 0.10 ounces

Does the sample data present sufficient evidence to conclude that the average weight is in fact less than 2.00 ounces (using alpha = 0.05)
1. Formulate the null and alternative hypotheses.
2. Determine the criterion for rejection or non-rejection of the null hypothesis.
3. Calculate the test statistic.
4. Compare the test statistic to the rejection region and make a judgment about the null and alternative hypotheses.
5. Interpret the statistical decision in terms of the problem.
6. Compute the observed "p" value in the hypothesis test and interpret this value. What does this mean?
