Tax= Tax %(Price of 2 Shirts + 50% of 3rd Shirt)
Tax= 7.1%[49.96+49.96+1/2(49.96)]
Tax= 0.071(49.96+49.96+24.98)
Tax= 0.071(124.90)
Tax= $8.8679

Total= Tax + Price of Shirts
Total= $8.8679 + $124.90
Total= $133.7689 or rounded $133.77

Mean Price= Total ÷ 3
Mean= $44.5893 or rounded $44.59

Answer: C) $44.59

Hope this helps! :)

How to use the results of part (b) and appropriate computation formulas to compute the sample variances s2 and sample standard d

anygoal [31]

$s^2=\displaystyle\sum\frac{(x-\bar x)^2}{n-1}=\frac1{n-1}\sum(x^2-2x\bar x+{\bar x}^2)=\frac{\displaystyle\sum x^2-2\bar x\sum x+{\bar x}^2}{n-1}$

where $\bar x=22$ is the mean. Since

$\sum x^2=2568$
$\sum x=110$

you have variance

$s^2=\dfrac{2568-2(22)(110)+22^2}{5-1}=37$

and so the standard deiviation is

$s=\sqrt{37}\approx6.083$
