5th-week assignment data

will you please give me the answer to Step3

• I use simple random method-The participants for this study were randomly selected using the simple random method. The survey was taken in different cities in the United States of America. The age ranges of the participants are between 16 years and 23 years. The selected sample size had nine males and eleven females. It is worth noting that the chosen sample group was students ranging between grade 11 and university second year.

Step 3: Using the data you collected for the Week 5 Lab (heights of 10 different people that you work withplusthe 10 heights provided by your instructor), discuss your method of collection for the values that you are using in your study (systematic, convenience, cluster, stratified, simple random). What are some faults with this type of data collection? What other types of data collection could you have used, and how might this have affected your study?

It is evident from the table above that the mean height of the 20 people is 67.55, while the standard deviation of the sample is 6.1428. My measurement of 66 inches is shorter than the average height of 20 people.
