Lactation promotes a temporary loss of bone mass to provide adequate amounts of calcium for milk production. The paper “Bone Mass Is Recovered from Lactation to Postweaning in Adolescent Mothers with Low Calcium Intakes” gave the following data on total body bone mineral content (TBBMC) (g) for a sample both during lactation (L) and in the postweaning period (P):
Subject L P
1 1928 2126
2 2549 2885
3 2825 2895
4 1924 1942
5 1628 1750
6 2175 2184
7 2114 2164
8 2621 2626
9 1843 2006
10 2541 2627
Estimate the difference between true average TBBMC for the two periods of concrete in a way that conveys information about precision and reliability. Does it appear plausible that the true average TBBMCs for the two periods are identical?

The computer-science aptitude score, x, and the achievement score, y (measured by a comprehensive final), were measured for 20 students in a beginning computer-science course. The results were as follows.
| x | 5 | 15 | 21 | 12 | 23 | 22 | 16 | 19 | 20 | 17 | 17 | 16 | 7 | 7 | 4 | 21 | 17 | 10 | 18 | 15 |
| y | 19 | 19 | 24 | 36 | 27 | 26 | 25 | 28 | 17 | 27 | 21 | 24 | 18 | 18 | 14 | 28 | 21 | 22 | 20 | 21 |
(a) Find the equation of the line of best fit. (Round your slope
to four decimal places and your y-intercept to three
decimal places.)
= + x
(b) Find se2. (Round your answer to
two decimal places.)

From Tesla’s website in 2014: “A year ago, Tesla introduced a Resale Value Guarantee that gives customers the option to return their Model S after three years for a known value. When combined with a car loan provided by Tesla’s banking partners, this program gives customers the functional equivalent of a lease.” Discuss how this program might help Tesla to solve the durable good monopoly problem described by Ronald Coase. Carefully explain the durable good problem and how this type of policy might relate to it.

A certain store gives its customers a discount on the goods they buy based on a peculiar manner.
The discount percentage is equal to each customer's remainder of weight to age, weight % age.
The maximum discount percentage allowed is 10.
If the remainder is greater than 10, the discount percentage is recomputed as the remainder of 10.
For example, a customer whose weight is 175 lbs and age 61, buys an item costing $60.97. The discount percentage = 175 % 61 = 53. As 53 is greater than 10, the discount percentage is recomputed as 53 % 10 = 3 percent.
Therefore, the discount amount is 0.03(60.97) = $1.83.
Write a class file called lastname_discount.java. Write methods to compute and return the discount percentage, the discount amount for each customer and the sum of all the discount amounts.
Write a demo file called lastname_discount_demo.java. Add two integer arrays containing the weight and age of customers and a double array containing the cost of goods (any number of customers greater than 10). Write an object to pass the three arrays into the class file and print the information returned by the three methods specified in the previous paragraph.
Extend the story line as you like (any reasonable) by clearly defining what it is. Add a fourth method (type your creation as a comment above the fourth method). Print the results of this fourth method below the first three outputs.
