Suppose a candy company representative claims that colored candies are mixed such that each large production batch has precisely the following proportions: 10% brown, 10% yellow, 30% red, 10% orange, 20% green, and 20%20% blue. The colors present in a sample of 410 candies was recorded. Is the representative's claim about the expected proportions of each color refuted by the data?

Color   Number of Candies
brown   80
yellow   101
red   70
orange   60
green   39
blue   60

3. It is commonly said that the average college student spends 10 hours per week on the Internet. It is common knowledge that the population standard deviation is 16 hours/week. You believe that the true average time that college students spend on the Internet should not be 10 hours per week, and decide to collect your own sample for a hypothesis test. You randomly sample 250 students from your college and find that on average they spent 12.5 hours a week online.

(a) Write and explain the null and alternative hypotheses.

(b) Write down the test statistic and explain in detail how it is distributed when the null hypothesis is true. Also explain in detail how the test statistic behaves when the null hypothesis is false.

(c) State the probability of Type I Error () you will use in designing your test.

(d) Show in a graph the test rejection region you would use. Be sure to label the distribution of the test statistic when the null hypothesis is true, and indicate where the probability of Type I Error is depicted in your graph.

(e) Show the confidence interval of the mean value and use the evidence to say whether reject or not reject the null hypothesis.

(f) Show the p value of the test statistics and use the evidence to say whether reject or not reject the null hypothesis.

Suppose you manage a local grocery store, and you learn that a very popular national grocery chain is about to open a store just a few miles away. Use the model of monopolistic competition to analyze the impact of this new store on the quantity of output your store should produce (Q) and the price your store should charge (P). What will happen to your profits? Please show graphically and explain your reasoning in detail. For example, how and why do profits change? How can that be seen on the graph? What could you do to defend your market share against the new store?
