A survey of the mean number of cents off that coupons give was conducted by randomly surveying one coupon per page from the coupon sections of a recent San Jose Mercury News. The following data were collected: 20¢; 75¢; 50¢; 65¢; 30¢; 55¢; 40¢; 40¢; 30¢; 55¢; $1.50; 40¢; 65¢; 40¢. Assume the underlying distribution is approximately normal. You wish to conduct a hypothesis test (α = 0.05 level) to determine if the mean cents off for coupons is less than 50¢.

3) Describe the type of correlation and interpret the correlation in the context of the data. Be specific in describing the magnitude, direction, and strength of the relationship. (12p)
4) Write out the null and alternative hypotheses and conduct a
hypothesis testing for the data. At the 1% level of significance,
is your test statistic statistically significant? Briefly explain
how you reached your conclusion.
For this question you must state followings: degrees of freedom,
one or two tailed hypothesis testing, the critical value, test
statistic, do you reject or fail to reject the null hypothesis.
(25p)
5) Find the equation of the regression line for the hours spent studying and test scores of students. What are the intercept (a) and slope (b) values of the regression formula, Ŷ = a+ bX for predicting test scores variable from hours spent studying variable. Write the formula replacing a and b by their respective numerical values (round off each element in the final formula to three decimal places). (15p)

Problem A Almond Delights is an almond grower. They have two primary products Premium Almonds and Choice Almonds. One acre of almond trees yields about 600 pounds of Premium and 1,400 pounds of Choice almonds at a cost of $6,000. A pound of Premium Almonds can be sold for $6.68. A pound of Choice can be sold for $4.28. Almond Delights further processes the 1,400 pounds of Choice almonds into 175 gallons of All Natural Almond Butter at an additional cost of $2,500. All Natural Almond Butter is sold for $40 per gallon. The 400 pounds of Premium Almonds is further processed into 450 pounds of Chocolate Almond Delights at an additional cost of $900. Each pound of Chocolate Almond Delights is sold for $12. 5.
5.What would gross profit be for Chocolate Almond Delights under the sales value at split-off method?
6. What would gross profit be for Chocolate Almond Delights under the NRV method?
7. What is the company's profit or loss when Premium almonds are further processed into Chocolate Almond Delights? (Enter a loss in parentheses.)
8. What is the company's profit or loss when Choice almonds are further processed into All Natural Almond Butter? (Enter a loss in parentheses.)

2) (10 point question) Many people love colorful and tasty tomatoes and an ambitious student in horticulture wants to breed such a tomato variety. He searched all the available tomato genetic resources, and found the two inbred lines he needed. One line produces the tomatoes with a colorful red-green-yellow mosaic pattern (rrTT), and the other strain is 'very tasty' (RRtt).
When the student crossed the two strains together, he made the following observations:
In the F1 generation, all the ripe tomatoes have a regular red color and a regular flavor. The student tasted tomatoes from over 40 individual plants, and was sick with regular tasting tomatoes.
In the F2 progeny, the student sampled 1000 tomato plants: 498 had red-color tomatoes with normal taste, 248 colorful tomatoes with normal taste, and 254 red-color tomatoes with great taste. He was disappointed not to find any colorful tomatoes with great taste. He then sampled another 2000 F2 plants: 998 had red-color tomatoes with normal taste, 511 colorful tomatoes with normal taste, 488 red-color tomatoes with great taste, and 3 colorful tomatoes with great taste; he was so happy to find what he wanted!!!
Based on these experimental results, he realized that the alleles he needs are recessive and the two genes are linked.
C) (2 points) The tomato genome has now been sequenced and genes on the chromosome are in the following order OPQRSTU. The respective physical distances on the chromosome between these seven genes are very similar. But we now know that there is a 'cold spot' between genes RT and 'hot spots' between PQ and TU. Draw a representation of the genetic map relative to the physical map (both maps are needed here) for this part of the tomato genome. Show the relative (approximate) locations of the genes on the two maps.
D) (2 points) What can you predict about the chromosome chromatin structure between the R and T genes?

NPV. Miglietti Restaurants is looking at a project with the following forecasted sales: first-year sales quantity of 33,000,with an annual growth rate of 4.00% over the next ten years. The sales price per unit will start at $44.00 and will grow at 2.00% per year. The production costs are expected to be 55% of the current year's sales price. The manufacturing equipment to aid this project will have a total cost (including installation) of $2,200,000. It will be depreciated using MACRS, and has a seven-year MACRS life classification. Fixed costs will be $330,000 per year. Miglietti Restaurants has a tax rate of 38%. What is the operating cash flow for this project over these ten years? Find the NPV of the project for Miglietti Restaurants if the manufacturing equipment can be sold for $140,000 at the end of the ten-year project and the cost of capital for this project is 7%.
1: What is the operating cash flow for this project for the first five years of the 10-year period??
2: for the last five years of the 10-year period?
3: What is the book value?
4: Calculate the gain or loss at disposal of the manufacturing equipment.
5: What is the after-tax cash flow at disposal?
