Here is а set оf dаtа fоr a randоm sample of eight customers from a local diner showing how much each customer paid for a tip in dollars:    2 7 1 0 3 5 4 2 In the edit menu bar running along the top of the answer box below, select the table icon. The table icon looks like:(If it is not visible in the menu bar, click on the three dots at the righthand edge of the menu bar to find it). When you click on the table icon, create a table by selecting 10 columns and 14 rows. If you can't figure out how to make the table, you will have to make your table as best you can using a few spaces to separate each column. Once the table is created, enter the tip data as you would in a datafile, and then using each of the definitional steps, find the variance and standard deviation. Clearly label each step and each value of interest, including the variance and SD.
