A large snack company claims that children enjoy their whole wheat snack equally as much as normal snacks. A study testing this claim on a SRS of 86 children were given both snack alternatives and then each child was asked which snack they preferred. The whole wheat snack was chosen by 48 children.
a) Using the 68-95-99.7 rule, if the snack company claims were true, you would expect ?̂ to fall between what two percent about 95% of the time?
b) Using your answer from a, is the snack company's claim correct?
c) Perform a significance test for α = 0.5

Three forces are applied to an object, as shown in the figure. F1 Baseline has a magnitude of 24.0 newtons (24.0 N) and is directed 30.0° to the left of the +y axis. F2 has a magnitude of 14.9 N and points along the +x axis. What must be the (a) magnitude and (b) direction (specified by the angle theta in the drawing) of the third force F3 such that the vector sum of the three forces is 0 N?

Management is concerned about the continued losses shown by the racing bikes and wants a recommendation as to whether or not the line should be discontinued. The special equipment used to produce racing bikes has no resale value and does not wear out.
Required:
1. What is the financial advantage (disadvantage) per quarter of discontinuing the racing bikes?
2. Should the production and sale of racing bikes be discontinued?
3. Prepare a properly formatted segmented income statement that would be more useful to management in assessing the long-run profitability of the various product lines.

47) "Fudgey" is a new brand of super-premium ice cream created for discerning ice-cream lovers who want rich creamy taste and unique flavors. Fudgey wants to distribute through specialty shops and also through supermarket chains. Fudgey is offering supermarket chains higher margins than all the other major ice cream brands in order to get in-store display space and promotion. Breyer's Ice Cream is the number 2 ice cream producer in the US and competes against Ben and Jerry's for the number 1 position.
Breyers managers are concerned that Fudgey may cut into their market share. They are considering running a comparative ad campaign against Fudgey in which they compare the quality of ingredients and consumer taste tests between the two brands. They ask you for your advice for their plan to run the comparative ad campaign. You advise them that
A. comparative advertising campaigns are viewed as unethical by more educated consumers
B. the comparative ad campaign may provide Fudgey with a source of free promotion and credibility with consumers
C. the comparative advertising campaign should have as its objective a reduction in the number of supermarkets distributing the brand
D. the comparative advertising can be an effective way for a market leader to deter entry of a new competitor
E. competitive advertising, if done creatively, can divert consumer's attention from a new product introduction

Consider two functions
f (x; y) = (x10)2 + (y + 2)2; and
g(x; y) = (x ? 10)2 + (x ? y + 5)4
Please implement a basic gradient descent algorithm using
python
Starting with (x; y) = (0; 0), and set up a xed learning rate =
0:5,
run the gradient descent algorithm for each function. Run for
10
iterations, and report both (x; y) and the function value at the
end of
each iteration.
Adjust the , and nd out the fastest convergence (smallest
function
value) after T steps (try T = 10 or 100).
