Question 1

City A has a crime rate of 45 per 1,000 residents and a population of 50,000. City B has a rate of 30 per 1,000 and a population of 200,000. Which city has more total crimes?

Accepted Answer

City B

Answer

City A: (45/1,000) × 50,000 = 2,250 crimes; City B: (30/1,000) × 200,000 = 6,000 crimes — City B has more.

Question 2

Worker A can complete a job in 6 hours and Worker B in 12 hours. How long will it take them working together?

Accepted Answer

4 hours

Answer

Combined rate = 1/6 + 1/12 = 2/12 + 1/12 = 3/12 = 1/4, so together they finish in 4 hours.

Question 3

A graph shows data points scattered with no discernible pattern. What type of correlation does this represent?

Accepted Answer

No correlation

Answer

A completely random scatter with no upward or downward trend indicates no correlation between the variables.

Question 4

An analyst says: 'Sales increased every year we ran the ad campaign; therefore the campaign caused the sales increase.' What logical flaw is present?

Accepted Answer

Correlation versus causation error

Answer

Assuming that a correlation between the ad campaign and sales proves causation is the classic correlation-does-not-equal-causation fallacy.

Question 5

A data set has a mean of 50 and a standard deviation of 5. What value is exactly two standard deviations above the mean?

Accepted Answer

60

Answer

Two standard deviations above the mean = 50 + (2 × 5) = 60.
