a. Sample statistic
b. Population parameter
c. Not mentioned
d. Data insufficient

Answer 1

The given value, which is the average weight of 157 lb for the 40 randomly selected members in the health and fitness club, is a sample statistic.

Step-by-step explanation:

The given value, which is the average weight of 157 lb for the 40 randomly selected members in the health and fitness club, is a sample statistic. A sample statistic represents a property of the sample, and since it is based on the data from the randomly selected members, it is a sample statistic. A population parameter would be the average weight of all members in the health and fitness club, but since we only have data for the randomly selected members, we can only calculate a sample statistic.
