TEAS 7 Math Practice Test

Correct Answer: C

Rationale: The correct answer is C: 29. To determine the range, subtract the smallest value from the largest value in the data set. Given the choices, 29 (C) has the widest range of values, which indicates the highest variability in the number of houses sold per year. Choices A, B, and D have smaller values, indicating less variability. Therefore, C is the correct answer as it provides the largest range, reflecting the potential difference in the number of houses sold annually.

Correct Answer: C

Rationale: Rationale: To find a reasonable estimate, divide the total distance by the number of days. 1480 miles / 5 days = 296 miles/day. The closest option is 300 miles/day (Choice C). This is the correct answer as it is the most accurate estimate of the daily distance. Choices A, B, and D are incorrect as they are either too low or too high compared to the calculated estimate, making them unreasonable choices.

Correct Answer: C

Rationale: The correct answer is C because in a negatively skewed distribution, the tail of the histogram extends to the left, indicating that there are more data points on the right side. In Group B, the histogram is negatively skewed, meaning it has a higher mean than Group A. Option A is incorrect because Group A is positively skewed, not negatively skewed. Option B is incorrect because Group A has a lower mean than Group B. Option D is incorrect because Group B has a higher mean than Group A due to its negatively skewed distribution.

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.
