Is the variance for the amount of money, in dollars, that shoppers spend on Saturdays at the mall the same as the variance for the amount of money that shoppers spend on Sundays at the mall? Suppose that the tables below show the results of a study:

Saturday:

65.8	59.9	82	63.2	100.2
78.8	118.4	74.3	109	77.3
61.8	92.9	84.5	79.6

(Note: The average and the standard deviation of the data are respectively 81.98 dollars and 17.802 dollars.)

Sunday:

58.8	98.5	74.1	87.1	77.7
99.8	86.3	65.1	60.3	86.8
64.5

(Note: The average and the standard deviation of the data are respectively 78.09 dollars and 14.732 dollars.)

Use a 10% significance level to test the claim that the standard deviation for the amount of money that shoppers spend on Saturday is different from the standard deviation for the amount of money that shoppers spend on Sunday. If normality plots are not provided assume that the samples are from normal populations.
