Week 7- Lab Assignment Student Name Math 225N Date Week 7- Lab Assignment In the words of El-Masri, “To draw conclusions about a study population, researchers use samples that they assume truly represent the population. The confidence interval (CI) is among the most reliable indicators of the soundness of their assumption. A CI is the range of values within which the population value being studied is believed to fall”. (Ele Massi, 2012). Step 3: Using the data you collected for Week 5 Lab (heights of 10 different people that you work with), discuss your method of collection for the values that you are using in your study. What are some faults with this type of data collection? What other type of data collection could you have used, and how might it have affected your study? During Week 5 Lab assignment, I collected data from my coworkers ages between 24-51, both male and female and from diverse backgrounds genetically. Some potential errors in the collection of data would be that there was no set group used. Both genders of various ages were used due to circumstances of available participants. In order to collect data more effectively, I would have asked 10 males and 10 females of similar ages. In addition, there was more data collected from females than males as there is limited male selection in the office, I work in. Step 4: Now use the Week 6 Spreadsheet (Links to an external site.) to help you with calculations for the following questions/statements. a) Give a point estimate for the average height of all people at the place where you work. Start by putting the ten heights you are working with into the blue data column of the spreadsheet. What is your point estimate, and what does this mean?
