Fertilizer: In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Thirteen randomly selected plots of land were treated with fertilizer A, and

10

randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results.

Part 1 of 3

Your Answer is correct

Explain why it is necessary to check whether the populations are approximately normal before constructing a confidence interval.

Since the sample size is ▼small, it is necessary to check that the populations are approximately normal.

Part 2 of 3

Your Answer is correct

Following are boxplots of these data. Is it reasonable to assume that the populations are approximately normal?

360 370 380 390 400 410 420 430 440 450

It ▼is reasonable to assume that the populations are approximately normal.

Part 3 of 3
Construct a  95% confidence interval for the difference between the mean yields for the two types of fertilizer. Let

μ1 denote the mean yield for fertilizer A. Use the TI-84 Plus calculator. Round the answers to one decimal place.

It is thought that basketball teams that make too many fouls in a game tend to lose the game even if they otherwise play well. Let x be the number of fouls more than (i.e., over and above) the opposing team. Let y be the percentage of times the team with the larger number of fouls wins the game.

Complete parts (a) through (e), given Σx = 14, Σy = 151, Σx² = 66, Σy² = 6005, Σxy = 457, and r ≈ −0.993.

(a) Verify the given sums Σx, Σy, Σx², Σy², Σxy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.)

Σx =

Σy =

Σx2 =

Σy2 =

Σxy =

(b) Find x, and y. Then find the equation of the least-squares line y = a + bx. (Round your answers for x and y to two decimal places. Round your answers for a and b to three decimal places.)

x=

y=

y = +   x

(c) Find the value of the coefficient of determination r². What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r² to three decimal places. Round your answers for the percentages to one decimal place.)

r² =

explained =     %

unexplained =    %

(d) If a team had x = 4 fouls over and above the opposing team, what does the least-squares equation forecast for y? (Round your answer to two decimal places.)

Analyzing, Interpreting and Capitalizing Operating Leases
YUM! Brands, Inc., reports the following footnote relating to its capital and operating leases in its 2015 10-K report ($ millions).

Future minimum commitments under noncancelable leases are set forth below. At December 26, 2015, the present value of minimum payments under capital leases was $169 million.

(a) Confirm that the implicit rate on YUM!'s capital leases is 7.634%.

Using a 7.634% discount rate and rounding the remaining lease life to three decimal places, compute the present value of YUM!'s operating leases. (Use a financial calculator or Excel to compute. Do not round until your final answers. Round each answer to the nearest whole number.)

* (Use subsequent rounded answers for calculation.)

Guinea worm is one of the human diseases that is on the verge of eradication. There is no preventive vaccine or treatment available for the disease. Discuss the public health prevention and control efforts that have enabled the near eradication of Guinea worm disease globally.
