Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: The correct answer is C: 0.84. To convert a percentage to a decimal, you divide by 100. In this case, 84% divided by 100 equals 0.84. Choice A is incorrect as 0.042 is not equivalent to 84%. Choice B is incorrect as 84% is not the same as 0.84. Choice D is incorrect as 0.42 is not the correct decimal form of 84%. Therefore, the correct representation of 84% in decimal form is 0.84.

Correct Answer: A

Rationale: The correct answer is A. When the sampling distribution of means is plotted, it follows the central limit theorem, which states that for a large enough sample size, the distribution of sample means will be approximately normally distributed regardless of the shape of the population distribution. This is because as sample size increases, the distribution becomes more normal due to the law of large numbers. Choice B is incorrect because the sampling distribution of means is not positively skewed. Choice C is incorrect because it is not negatively skewed. Choice D is incorrect as there is a predictable shape to the distribution, which is approximately normal due to the central limit theorem.

Correct Answer: C

Rationale: To determine how many questions the student answered correctly, we can calculate 85% of 20. 85% of 20 = 0.85 * 20 = 17. Therefore, the student answered 17 questions correctly. Option A, B, and D are incorrect because they do not correspond to the calculated result. Option A is too low, B is close but still lower, and D is too high.

Correct Answer: B

Rationale: To calculate average speed, you divide the total distance by the total time. In this case, 150 miles divided by 3 hours equals 50 mph. Therefore, choice B is correct. Choice A is incorrect as it is too low. Choice C and D are incorrect as they are too high.
