To investigate if autism is marked by different brain growth patterns in early life, studies have tried to link brain size in infants and toddlers to autism. Suppose the whole-brain volume in non-autistic toddlers is known to be 1200 milliliters, on average. One study based on a sample size of 25 autistic toddlers had a sample mean volume of 1280 ml with a standard deviation of 230 ml.
a. Calculate a 95% confidence interval for the whole-brain volume of autistic toddlers. Given: ?"#$%& ∗ =2.064

b. Do the results from this study suggest that autistic toddlers have the same whole-brain volume as non-autistic toddlers, on average? Explain your answer.
c. If you used the same data from this study and calculated a 90% confidence interval, would it be wider or narrower than the 95% interval?
d. If the data from this study had the same mean and standard deviation, but was from a sample of size 15 instead of 25, would the 95% confidence have been wider or narrower?

Bad Sporting Goods makes cleats that are very popular in the spring and early summer season. Units sold are anticipated as follows:

Total units are 31,500

If seasonal production is used, it is assumed that inventory will directly match sales for each month and there will be no inventory buildup. The production manager thinks the preceding assumption is too optimistic and decides to go with levels of production to avoid being out of merchandise. He will produce the 31,500 units over 4 months at a level of 7,875 per month.

a. What is the ending inventory at the end of each month? Compare the unit sales to the units produced and keep a running total.

b. If the inventory costs $12/unit and will be financed at the bank at a cost of 12%, what is the monthly financing cost and the total for the four months? (use .01 as the monthly rate).

Convince college students to start investing for their retirement early. It should compare the wealth outcomes when starting at 20 versus starting at 40 and demonstrate the impact on the final portfolio when investing in riskier/higher return financial instruments (compare 2-3 alternatives like ETFs, stocks, bonds) rather than keeping one’s money in low-interest-bearing savings accounts.

Scenario: In the early 1990s, Stella Liebeck, 79 ordered a cup of coffee at McDonald's. She accidentally spilled the coffee on her lap and suffered serious burns. She sued McDonald's for negligence, among other things.
Liebeck v. McDonald's Restaurants, P.T.S., Inc., No. D-202 CV 93 02419, 1995 WL 360309 (Bernalillo County, N.M. Dist. Cut. August 18, 1994).
Support the plaintiff, Liebeck and highlight the strengths and weaknesses of the plaintiff to a basic negligence action only.

An educator wants to determine whether early exposure to school will affect IQ. He enlists the aid of the parents of 12 pairs of preschool-age identical twins who agree to let their twins participate in his experiment. One member of each twin pair is enrolled in preschool for 2 years, while the other member of each pair remains at home. At the end of the 2 years, the IQs of all the children are measured.

Tom decides to get an early start on retirement saving and, beginning at age 22, he invests $4,000 per year in a Roth IRA for 10 years in a row. At that point, he stops contributing to the account but leaves the money invested until age 65 (a period of 33 years). Harry doesn’t start investing until he’s 32 but from then on invests $5,000 in a Roth IRA each year for 33 years until retirement at age 65. If both men earn 9.875 percent per year on their investments, compounded annually, what are their final account values? Who has accumulated more money? How much more?

A. Suppose we test the proportions of people who like having a cup of coffee early in the morning for two populations: H0 : p1= p2 vs Ha : p1< p2. The sample sizes for these two population are n1= n2=400 and the numbers of people who like coffee are x1 =160 and x2=200 respectively. What is the value of the test statistics?

a. -2.8571        b. -2.8427

c. -2.8866        d. -2.8284

B. Suppose we take Type I error level to be α = 0.01 in the above population proportion testing. What is your conclusion?

a. Reject H0.   b. Accept H0 c. Do not know.

From the time of early studies by Sir Francis Galton in the late nineteenth century linking it with mental ability, the cranial capacity of the human skull has played an important role in arguments about IQ, racial differences, and evolution, sometimes with serious consequences. (See, for example, S.J. Gould, "The Mismeasure of Man," .) Suppose that the mean cranial capacity measurement for modern, adult males is cc (cubic centimeters) and that the standard deviation is cc. Complete the following statements about the distribution of cranial capacity measurements for modern, adult males. (a) According to Chebyshev's theorem, at least ? of the measurements lie between 565 cc and 1481 cc. (b) According to Chebyshev's theorem, at least 36% of the measurements lie between and . (Round your answer to the nearest integer.) (c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 99.7% of the measurements lie between and . (d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ? of the measurements lie between 565 cc and 1481 cc.

A story spoiler gives away the ending early. Does having a story spoiled in this way diminish suspense and hurt enjoyment? A study¹ investigated this question. For twelve different short stories, the study’s authors created a second version in which a spoiler paragraph at the beginning discussed the story and revealed the outcome. Each version of the twelve stories was read by at least 30 people and rated on a 1 to 10 scale to create an overall rating for the story, with higher ratings indicating greater enjoyment of the story. The ratings are given in Table 1 and stored in StorySpoilers. Stories 1 to 4 were ironic twist stories, stories 5 to 8 were mysteries, and stories 9 to 12 were literary stories. Test to see if there is a difference in mean overall enjoyment rating based on whether or not there is a spoiler.
