20. Find P(A|B).
a. 16/144
b. 2/4
c. 2/144
d. 4/16

23. A correlation coefficient of 0.1 indicates that a scatterplot of the data follows:
a. a strong, positive linear pattern
b. a weak, negative linear pattern
c. no pattern
d. a weak, positive linear pattern

24. Choose the correct interpretation for the 95% confidence interval estimate of the true
population mean IQ score among adult Americans: (70, 130)
a. We are 95% confident that a randomly selected adult American has an IQ score
between 70 and 130.
b. We have a 95% chance to capture the true population mean IQ score among adult
Americans in between 70 and 130.
c. We are 95% confident that the true population mean IQ score among adult Americans is
between 70 and 130.
d. The probability that a randomly selected adult American has an IQ score between 70
and 130 is 95%.
