Question 1 of 5

What kind of relationship between a predictor and a dependent variable is indicated by a line that travels from the bottom-left of a graph to the upper-right of the graph?

Correct Answer: A

Rationale: The correct answer is A: Positive. A line traveling from bottom-left to upper-right on a graph indicates a positive relationship between the predictor and dependent variable. As the predictor increases, the dependent variable also increases. This is because the slope of the line is positive, showing a direct relationship between the two variables. In contrast, a negative relationship (choice B) would be indicated by a line traveling from top-left to bottom-right, where the dependent variable decreases as the predictor increases. Choices C (Exponential) and D (Logarithmic) refer to specific nonlinear relationships, which are not indicated by a line with a positive slope.

Question 2 of 5

Which measure for the center of a small sample set would be most affected by outliers?

Correct Answer: A

Rationale: The correct answer is A: Mean. The mean is calculated by summing all values and dividing by the number of values. Outliers can significantly skew the mean because they have a greater impact on the total sum. The median (B) is less affected by outliers since it is the middle value when data is sorted. The mode (C) is the most frequent value and is not affected by outliers. Choice D is incorrect as outliers can impact the mean in a small sample set.

Question 3 of 5

Calculate the sum of the numbers from 1 to 6:

Correct Answer: B

Rationale: To calculate the sum of numbers from 1 to 6, we use the formula for the sum of an arithmetic series: n/2 * (first term + last term). In this case, n=6, first term=1, last term=6. So, 6/2 * (1 + 6) = 3 * 7 = 21. Therefore, the correct answer is B: 21. Explanation for other choices: A (30): Incorrect, as it is not the sum of numbers from 1 to 6. C (15): Incorrect, this is the sum of numbers from 1 to 5, not 1 to 6. D (13): Incorrect, this is the sum of numbers from 1 to 4, not 1 to 6.

Question 4 of 5

How much did he save from the original price?

Correct Answer: B

Rationale: The correct answer is B: $212.50. To determine how much he saved, you need to find the difference between the original price and the final price after the discount. The original price is $425 and the final price is $212.50 after a 50% discount. Subtracting $212.50 from $425 gives us the amount saved, which is $212.50. The other choices are incorrect because they do not reflect the actual savings based on the given information. Choice A is half of the original price, choice C is the discount amount, and choice D is the original price discounted by $25, not the actual savings.
