1. Mr and Mrs Smith and Mr and Mrs Doe both had baby girls at Bay Hospital. The hospital mixed up which girl belonged to which couple. Baby X is blood type O, Baby Y is blood type A. Mr Smith is blood type AB. Mr Doe is blood type B. Both Mrs Smith and Mrs Doe are blood type A. Can you solve which baby goes to which couple? In the form below, list all possible genotypes and indicate the parents for each baby.

1.Weights, in pounds, of ten-year-old girls are collected from a neighborhood. A sample of 26 is given below. Assuming normality, use Excel to find the 98% confidence interval for the population mean weight μ. Round your answers to three decimal places and use increasing order.Weight

Julia wants to estimate the percentage of people who submit their tax returns online. She surveys 330 individuals and finds that 65 submit their tax returns online.

Find the margin of error for the confidence interval for the population proportion with a 95% confidence level.

Use the table of common z-scores above.

• Round the final answer to three decimal places

Here are summary statistics for randomly selected weights of newborn​ girls: n =191​, x̅ = 33.2 ​hg, s = 6.1 hg. Construct a confidence interval estimate of the mean. Use a 90​%

confidence level. Are these results very different from the confidence interval 32.9 hg < μ < 34.3 hg with only 19 sample​ values, x̅ = 33.6 ​hg, and s = 1.7 ​hg?

A. What is the confidence interval for the population mean μ​?

____ hg < ​​​μ​ < ____ hg (Round to one decimal place as​ needed.)

B. Are the results between the two confidence intervals very​ different?

a) Yes, because the confidence interval limits are not similar.

b) No, because each confidence interval contains the mean of the other confidence interval.

c) ​No, because the confidence interval limits are similar.

d) Yes, because one confidence interval does not contain the mean of the other confidence interval.

Presume for a minute that (OK, so maybe this premise was slightly borrowed from the movie The Stepfather, the one from the 1980s, not the terrible recent one), a new college professor moves into town and gets a job teaching math. The new professor is charming and funny and everyone likes him. The dean introduces him to his daughter and they begin an engagement. Shortly thereafter, he begins acting possessive and increasingly paranoid. He begins staying after class, very late in fact. Soon, a chemistry student goes missing, followed by an art student. In a very dramatic car chase scene involving the dean's daughter and the professor, the professor is expelled from the windshield of his car and eaten by an alligator. A fingerprint check establishes that he previously lived in Richmond, VA under a different name and worked as a social worker and was suspected in the disappearance of several college students.

Assume the college did not do a background check and the background check would have easily discovered this information. What would they be liable for? In today's #metoo environment, what liability can companies incur from failure to do due diligence? What about marijuana? It's lawful in many states now, does that absolve the employer's liability for accidents on the job?

Timothy is a seven year old boy, his mother takes him to the pediatrician for review. Its weight is 31 kg and corresponds to the 95th percentile; their height is 127 cm and they are between the 75th and 90th percentiles for their age. His body mass index is 19.25 kg / m2, which is just above the 95th percentile for his age. Their growth percentiles have increased in recent years. Timothy's mother expresses her concern to the pediatrician about the weight of her son; his brothers, one older and one younger than him, are slimmer. Timothy's mother is obese, but her father is a normal weight for height. Timothy is in his second year of elementary school and takes the school bus both to go to school and to return. She participates in her school's school breakfast program, but her parents give her extra money to buy, if she wants, some of the food sold in the cafeteria or the vending machines. After school, Timothy and his siblings stay at home with a babysitter until one of their parents returns from work. Timothy usually watches television or entertains himself with video games after school; Their parents leave treats (chips, cookies, and soft drinks) at home for their children to eat after school. The mother usually prepares the evening meal, which consists of meat, starch, vegetables and a dessert. After dinner, Timothy does his homework and then watches more television with his parents. He often has ice cream before going to the cabin.

The Classical School and the identification of a local/global problem.

a) Identify a local/global problem that might be caused by the application of a policy that is based on a theory or concept of the Classical school.

Your answer needs to provide at least three paragraphs.

The first paragraph identifies and explains in your own words the concept or theory of the Classical School

The second paragraph identifies and explains the a local/global problem.

The third paragraph explains the connection between the economic concept/theory and the local problem

Conscientiousness is a trait which implies discipline, dependability, and a heightened sense of personal responsibility. A school administrator wants to compare conscientiousness between high school and university students. He recruits 10 university and 15 high school students and measures their conscientiousness scores on a scale from 1 to 20 where 20 indicates greater conscientiousness. The university students have a mean conscientiousness score of 10 with a standard deviation of 1.5. The high school students have a mean conscientiousness score of 8 with a standard deviation of 1.7. In addition, standard error = .646. Is there a difference in conscientiousness between high school and university students?

a. Identify the IV, IV levels, and DV.

IV:
Levels:
DV:

b. Is this experiment a paired-samples or independent-samples design?

c. State null and alternative hypotheses in words.

H₀:
H₁:

d. Conduct a statistical test of the hypothesis

t( ) =

e. Decide whether to reject or retain the null hypothesis.

f. Interpret your results.
