Question

suppose a survey of 540 women in the united states found that 70% are the primary investor in their household. which part of the survey represents the descriptive branch of statistics? make an inference based on the results of the survey

choose the best statement of the descriptive statistic in the problem

a. about 70% of women in the united states are the primary investor in their household

b. 540 women were surveyed

c. there is an association between the 540 women and being the primary investor in their household

d. 70% of women in the sample are the primary investor in their household

Explanation:

Step1: Recall descriptive statistics

Descriptive statistics summarize data from a sample. Here, we analyze each option.

Step2: Analyze option A

This is an inference about the population, not descriptive statistics for the sample.

Step3: Analyze option B

The number of women surveyed is just a sample - size fact, not a descriptive statistic about the key variable (primary - investor status).

Step4: Analyze option C

This statement about association is more related to inferential statistics rather than descriptive.

Step5: Analyze option D

70% of women in the sample being primary investors is a descriptive statistic as it summarizes a characteristic of the sample.

Answer:

D. 70% of women in the sample are the primary investor in their household
