In December​ 2004, 44​% of students in high school were satisfied with the lunches supplied through the school. In May​ 2010, an organization conducted a poll of 766 students in high school and asked if they were satisfied with the lunches supplied through the school. Of the 766 ​surveyed, 299 indicated they were satisfied. Does this suggest the proportion of students satisfied with the quality of lunches has​ decreased? ​(a) What does it mean to make a Type II error for this​ test? ​(b) If the researcher decides to test this hypothesis at the alpha=0.10 level of​ significance, compute the probability of making a Type II​ error, beta​, if the true population proportion is 0.39. What is the power of the​ test? ​(c) Redo part​ (b) if the true population proportion is 0.43.

In December​ 2004, 54​% of students in high school were satisfied with the lunches supplied through the school. In May​ 2010, an organization conducted a poll of 1045 students in high school and asked if they were satisfied with the lunches supplied through the school.

A) A ski school faces two demand curves. The demand by Locals is QL = 200 – 0.5PL, and the demand by Visiting tourists is QV = 300 – 0.5PV. The marginal cost of serving either locals or visitors is constant at MC = $50. If the ski school CANNOT practice third-degree price discrimination and must charge a single price to all customers, it will charge $_____

B) A ski school faces two demand curves. The demand by Locals is Q_L = 200 – 0.5P_L, and the demand by Visiting tourists is Q_V = 300 – 0.5P_V. The marginal cost of serving either locals or visitors is constant at MC = $50. If the ski school practices third-degree price discrimination, it will charge Locals a price of P_L = $ ______ and Visitors a price of P_V = $ _______

Do teachers find their work rewarding and satisfying? An article in Psychological Reports reported the results of a survey of a random sample of 395 elementary teachers and 266 high school teachers. Of the elementary school teachers, 224 said that they were very satisfied with their jobs, whereas 166 of the high school teachers were very satisfied with their work.

a. Based on this data, is it reasonable to conclude that the proportion of very satisfied teachers is different for elementary teachers than it is for high school teachers? Please state conclusion properly with context.

b. Construct and interpret a 95% Confidence Interval in the context of the above scenario.

c. How do the results in Part a and b compare? Do the results contradict each other?

Assignment 1:

It is known that achievement test scores of all high school seniors in a state (in the US) have mean 60 and variance 64. On a large high school, located in a low socio economic area, a small group of senior students set out to investigate the performance of their own school. They collected a random sample of ??=100 achievement test scores from fellow students. Analyzing the results, it was found that the sample mean achievement test score was 58.

A) Is there evidence to suggest that this high school is performing poorly? Look at the hint below and provide an explanation.

(Hint: find the probability that the sample mean achievement test score is at most 58, assuming that the true mean score is 60. In the computation, use ? = 8)

Amazon Beverages produces and bottles a line of soft drinks using exotic fruits from Latin America and Asia. The manufacturing process entails mixing and adding juices and coloring ingredients at the bottling plant, which is a part of Mixing Division. The finished product is packaged in a company-produced glass bottle and packed in cases of 24 bottles each.

Because the appearance of the bottle heavily influences sales volume, Amazon developed a unique bottle production process at the company’s container plant, which is a part of Container Division. Mixing Division uses all of the container plant’s production. Each division (Mixing and Container) is considered a separate profit center and evaluated as such. As the new corporate controller, you are responsible for determining the proper transfer price to use for the bottles produced for Mixing Division.

At your request, Container Division’s general manager asked other bottle manufacturers to quote a price for the number and sizes demanded by Mixing Division. These competitive prices follow:

^a An equivalent case represents 24 bottles.

Container Division's cost analysis indicates that it can produce bottles at these costs:

These costs include fixed costs of $850,000 and variable costs of $4.50 per equivalent case. These data have caused considerable corporate discussion as to the proper price to use in the transfer of bottles from Container Division to Mixing Division. This interest is heightened because a significant portion of a division manager’s income is an incentive bonus based on profit center results.

Mixing Division has the following costs in addition to the bottle costs:

The corporate marketing group has furnished the following price–demand relationship for the finished product:

a. Amazon Beverages has used market price–based transfer prices in the past. Using the current market prices and costs and assuming a volume of 1.35 million cases (Enter your answers in thousands of dollars.)
