Collect measurements (such as shoe size, height, or age) from ten different people, and answer the following questions. This is a sample but it is not a random sample. Write up your answers and submit them with your homework for grading. Make sure you show all your work. Find the mean, median, and mode for your sample. Find the sample standard deviation of your sample. Why is this not a random sample?

Solution

we should collect the measurments like shoe , height and age the from yhebook which you have given page numbers.

and also here we should find mean, meridian, mode.

mean is also called average = 39+15+20+18+47+32+10+25+2+58

= 266/10

= 26.6

here the meridian is the middlest one

here the values are 39,15,20,18,47,32,10,25,2,58

here we have the middle values 47,32

therefore meridian = 47+32/2

= 39.5

mode is the value which is erpeated more than one time.
