Data has been collected from a representative of a well-defined population to answer the question: "How much money does the average senior male at Normal Community High School have in his pockets at the end of the school day on Friday?" The next step in the study is to:

a. determine the margin of error
b. summarize the data with a sample statistic
c. use the collected data to make inferences about the population
d. summarize the data with a sample parameter

I chose b?

Agree.

Correct! The next step in the study would be to summarize the data with a sample statistic.

Summarizing the data with a sample statistic involves calculating descriptive measures like the sample mean, median, or mode to understand the central tendency and variability of the data collected from the representative of the population. This will provide insights into how much money the average senior male at Normal Community High School has in his pockets at the end of the school day on Friday based on the collected data.

Option b, summarizing the data with a sample statistic, aligns with this step.

You chose option b, which is to summarize the data with a sample statistic. This step involves analyzing the collected data and calculating descriptive statistics such as mean, median, mode, standard deviation, etc., to summarize the characteristics of the sample. These statistics provide a snapshot of the data and help in understanding the average and spread of the values collected from the senior males at Normal Community High School.
