The Following Table gives the sales for the Sasquatch Men's Shoe store:

5 , 12

7 , 50

9 , 46
10 , 37
11 , 14
12 , 11

1)determine the mean for the distribution, correct to 2 decimal places.

2) Determine the standard deviation, correct to 2 decimal places .

3) set up the frequency graph for the data. does the distribution appear to be normal?

What don't you understand about these problems?

apply the formula for the given data.

to find the mean, would i go 4x8x5x12x6x31x7x50x8x58...... / 100 ?

No. Don't include the shoe size in the mean.

Add the frequencies. Divide the sum by 9 to find the mean.

267?

9
=29.666

Yes. Rounded to two decimal places its 29.67

Thank you, for this question? determine the standard deviation, correct to 2 decimal places.

Study this site to learn how to find the standard deviation.
