LAB

Your instructors will post 10 data values to use for this lab. The data values represent the HEIGHTS of 10 people. This data set is posted in the FILES area, in the “Lab Files” folder. (NOTE: This is NOT the data used in the lab video, which is about midterm grades. Do not use the midterm grades data.)

1a. Gather 10 MORE heights on your own to add to the 10 provided by your instructor. Do the following: Survey or measure 10 people to find their heights. Determine the mean and standard deviation for the 20 values by using the Week 3 Excel spreadsheet. (Round statistics to two decimals.)

Sample standard deviation =  

1b. Post a screen shot in the space BELOW of the portion of the spreadsheet that helped you determine these values. The screenshot should show ALL 20 pieces of data. Make sure the instructor data is listed first and then your data is listed under.
