1.

a) Find the sample standard deviation of the following data.

8 40 46 47 49 50

Show the calculations by using the following table

The mean of these numbers is 40 (so in the second column we subtract 40 from each of the numbers).

x

8 -32 1024

40 0 0

46 6 36

47 7 49

49 9 81

50 10 100

Sum = 1290

To get the standard …

The solution provides the mean and standard deviation for the given data.
