7. A researcher was once criticized for falsifying data. Among his data were figures obtained from 55 groups of rats​, with 44 individual rats in each group. These values were given for the percentage of successes in each​ group: 53%,​ 58%, 63%, ​46%, 48% nothing. ​What's wrong with those​ values?

A. All percentages of success should be multiples of 5. The given percentages cannot be correct.

B.All percentages of success should be multiples of 4.The given percentages cannot be correct.

C.All percentages of success should be multiples of 25. The given percentages cannot be correct.

D.All percentages of success should be multiples of 8. The given percentages cannot be correct.

8. Determine whether the underlined number is a statistic or a parameter. In a study of all 4229 employees at a college,  it is found that Modifying 45 % with underline own a computer.

A. Parameter because the value is a numerical measurement describing a characteristic of a population.

B. Statistic because the value is a numerical measurement describing a characteristic of a population.

C. Statistic because the value is a numerical measurement describing a characteristic of a sample.

D. Parameter because the value is a numerical measurement describing a characteristic of a sample.

9. Determine whether the value given below is from a discrete or continuous data set. In a test of a method of gender selection comma 683 couples used the XSORT method and 528 of them had baby girls.

A. A continuous data set because there are infinitely many possible values and those values can be counted can be counted.

B. A discrete data set because there are a finite number of possible values

C.A continuous data set because there are infinitely many possible values and those values cannot be counted

D.The data set is neither continuous nor discrete.

10. Determine whether the value is from a discrete or continuous data set.

Number of coins in a jar is 78

Is the value from a discrete or continuous data​ set?​​

A. Continuous

B. Discrete

11. Determine whether the description corresponds to an observational study or an experiment.

Thirty university students are divided into two groups. One group receives free tutoring in mathematics, the other doesn't. After one semester, scores on final mathematical examinations are compared.

Does the description correspond to an observational study or an​ experiment?

A. Observational study

B. Experiment

Medicare is a social insurance program for elderly individuals that covers the cost of healthcare if they fall sick. Suppose a country decides to enact a similar program called BN-care because it is discovered that many elderly citizen are going bankrupt after they get sick, as the result of high medical costs.

a. What does this bankruptcy situation tell us about private insurance markets? Why might this be the case?

b. Why are consumers willing to pay for insurance, given that the payment reduces their expected lifetime income?

c. Suppose the enactment of BN-care only reduces the percent of elderly who go bankrupt after they get sick by 50%.

What might be going on? (multiple answers possible)

The issue of rent control adds politics to the issue of pricing, for it asks us whether governments should fix prices below the free-market price. The two political positions most directly at issue are: Classical Liberalism: People should be treated as self-responsible adults who are able to trade freely for the goods and services they need and want. Paternalism: Like a father (pater) or mother (mater), the government should use its power to set prices at a level the poorer can afford. Does this seem an accurate characterization of the difference between the two parties? The classical liberals believe people should be equal in freedom and self-responsibility, while the paternalists believe people should be equal in wealth and bargaining power?

Who is Tim Horton's leader? Provide a description of him/her. What contributions he/she has made to the company?

Big Al Athletic Apparel annually sells 20,000 University of West Florida branded cotton T-shirts through distributors who then sell the shirts for $15 to retailers like Dick’s Sporting Goods who then sell them on to consumers for $25 each. Big Al’s costs of goods are $5 per shirt and they are required to pay a licensing fee to UWF for $1 for every shirt that they sell via distributors. This fee is only charged on those shirts sold to the distributors. The distributors’ margins are 20%.

1. Create a Value Chain for the shirts by filling in the blanks

2. After a very disappointing football and basketball season for the Gators, Big Al’s is considering lowering the price to increase T-shirt demand. If Big Al’s decided to reduce its price on the T-Shirts by $50, how additional units would it need to break even?

Multiple Choice

1. Big Al’s new contribution margin after the price discount is:

1. $6
2. $4.50
3. $3.50
4. $2.50
5. None of these

2. What is the incremental number of units that Big Al’s needs to sell to break even on the price discount?

1. 20,000
2. 14,286
3. 34,286
4. 50,000
5. None of these

A university lecturer in History hypothesizes that more time studying predicts better exam performance. Before the next exam, the lecture asks students in the class the average amount of time (in minutes) they spend in the library per day. The data are below. What can be concluded with α = 0.05?

a) What is the appropriate statistic?
---Select--- na Correlation Slope Chi-Square
Compute the statistic selected above:  

b) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
Critical value =  ; Test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

c) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
Effect size =  ;   ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

Students who spend more time studying have better exam performance.Students who spend more time studying have worse exam performance.    Students time studying does not predict exam performance.
