BMST - Basic Math and Science Data Interpretation and Probability Questions and Answers 2

Question 1

A dataset has values: 4, 7, 7, 9, 13. What is the median?

Accepted Answer

7

Answer

The data is already sorted. The middle value (3rd of 5) is 7.

Question 2

If you flip a fair coin twice, what is the probability of getting heads both times?

Accepted Answer

1/4

Answer

P(H and H) = 1/2 × 1/2 = 1/4, since the flips are independent events.

Question 3
