The weighted weekly mean of t-shirt sales is 5.6.
The total number of weeks reported is the sum of the frequency column.
1+4+7+3 = 15 weeks
The total number of t-shirts sold is calculated as the product of the quantity of t-shirts sold and the number of weeks during which those t-shirts were sold.
2*1 + 4*4 + 6*7 + 8*3 = 2 + 16 + 42 + 24 = 84
