In a study measuring the average hours worked per week by different types of hospital staff (such as nurses and physicians), what are the dependent and independent variables?

  • A. The dependent variable is Nurses. The independent variable is Physicians.
  • B. The dependent variable is Physicians. The independent variable is Nurses.
  • C. The dependent variable is Hospital Staff. The independent variable is Average hours worked per week.
  • D. The dependent variable is Average hours worked per week. The independent variable is Hospital Staff.
Correct Answer: D

Rationale: In this study, the dependent variable is the 'Average hours worked per week,' as it relies on the different types of 'Hospital Staff' (the independent variable). The amount of time worked per week varies based on the category of staff being considered. Therefore, the correct choice is D. Choices A and B incorrectly assign the dependent and independent variables to specific staff categories (Nurses and Physicians), which are actually different elements within the study. Choice C incorrectly defines the dependent variable as 'Hospital Staff,' when in fact, it is the 'Average hours worked per week' that is dependent on the type of staff.

The cost of renting a bicycle is $3.60 per hour. Which equation shows the best relationship between the total cost (C) and the number of hours (h) rented?

  • A. C = 3.60h
  • B. C = h + 3.60
  • C. C = 3.60h + 10.80
  • D. C = 10.80h
Correct Answer: A

Rationale: The best relationship is C = 3.60h because the cost increases by $3.60 for each hour of rental. This equation represents a linear relationship where the total cost (C) is directly proportional to the number of hours rented (h). Choice B (C = h + 3.60) is incorrect because it wrongly assumes a fixed additional cost of $3.60 regardless of the number of hours rented. Choice C (C = 3.60h + 10.80) is incorrect as it overestimates the initial cost. Choice D (C = 10.80h) is incorrect as it implies a constant rate of $10.80 per hour, which is not the case.

Approximately what percentage more staff members at Hospital Y are female than at Hospital X?

  • A. 5
  • B. 10
  • C. 15
  • D. 20
Correct Answer: B

Rationale: To find the percentage more staff members at Hospital Y are female than at Hospital X, we first calculate the percentage of female staff members at each hospital. For Hospital Y: (90 / 183) x 100 ≈ 49.2%. For Hospital X: (97 / 250) x 100 ≈ 38.8%. The difference between these percentages is approximately 10%, making choice B the correct answer. Choice A, 5%, is too low as the difference is greater. Choice C, 15%, and choice D, 20%, are both too high as the actual difference is closer to 10%.

Pernell received the following scores on five exams: 81, 92, 87, 89, and 94. What is the approximate average of these scores?

  • A. 81
  • B. 84
  • C. 89
  • D. 91
Correct Answer: C

Rationale: To calculate the average of Pernell's scores, add all the scores together and then divide by the number of scores.
(81 + 92 + 87 + 89 + 94) = 443.
Now, divide 443 by 5:
443 · 5 = 89, which is the average score.

In the town of Ellsford, there are approximately 1,450 residents who attend church weekly. If around 400 of them attend Catholic Churches, what percentage of churchgoers in Ellsford attends Catholic Churches?

  • A. 23%
  • B. 28%
  • C. 36%
  • D. 42%
Correct Answer: B

Rationale: To find the percentage of churchgoers who attend Catholic Churches, divide the number of Catholic churchgoers by the total number of churchgoers and then multiply by 100.
(400 · 1,450) 100 ≈ 27.59%, which rounds to 28%.

A mathematics test has a 4:2 ratio of data analysis problems to algebra problems. If the test has 18 algebra problems, how many data analysis problems are on the test?

  • A. 24
  • B. 28
  • C. 36
  • D. 38
Correct Answer: C

Rationale: The ratio of 4:2 simplifies to 2:1. This means that for every 2 algebra problems, there is 1 data analysis problem. If there are 18 algebra problems, we can set up a proportion: 2 algebra problems correspond to 1 data analysis problem. Therefore, 18 algebra problems correspond to x data analysis problems. Solving the proportion, x = 18 * 1 / 2 = 9. Hence, there are 9 data analysis problems on the test. Therefore, the total number of data analysis problems on the test is 18 (algebra problems) + 9 (data analysis problems) = 27.
