Question

In a survey of 7,786 randomly selected adults living in Germany, 5,840 said they exercised for at least 30 minutes three or more × per week. Give the value of the best estimate of the population parameter. Round your answer to two decimal places.

a) 0.75
b) 0.80
c) 0.85
d) 0.90

Answer 1

The best estimate of the population parameter is 0.75.

Step-by-step explanation:

To find the best estimate of the population parameter, we can use the formula:

best estimate of population parameter = number of individuals in sample / total number of individuals surveyed

In this case, the number of individuals in the sample who said they exercised for at least 30 minutes three or more times per week is 5,840. The total number of individuals surveyed is 7,786. Using the formula, we have:

best estimate of population parameter = 5,840 / 7,786 = 0.74935853956

Rounding to two decimal places, the best estimate of the population parameter is approximately 0.75.
