U.S. and European shoe sizes: To convert a European male shoe size “E” to an American male shoe size “A,” the formula $A=0.76 E-23$ can be used. Lillian has five sons in the U.S. military, with shoe sizes ranging from size 9 to size 14 $(9 \leq A \leq 14) .$ What is the corresponding range of European sizes? Round to the nearest half-size.

Shoe Sizes The table shows women’s shoe sizes in the United States and the corresponding European shoe sizes. Let $y=g(x)$ epresent the function that gives the women’s European shoe size in terms of $x,$ the women’s U.S. size.$$\begin{array}{c|c}\hline \text { Women’s U.S. } & {\text { Women’s European }} \\ \hline \text { shoe size } & {\text { shoe size }} \\ \hline 4 & {35} \\ {5} & {37} \\ {6} & {38} \\ {7} & {39} \\ {8} & {40} \\ {9} & {42} \\ \hline\end{array}$$(a) Is $g$ one-to-one? Explain.(b) Find $g(6)$ .(c) Find $g^{-1}(42)$(d) Find $g\left(g^{-1}(39)\right)$(e) Find $g^{-1}(g(5))$

A study was conducted on shoe sizes of students, reported in European sizes. For the women, the mean size was 39.84 with a standard deviation of 1.63. To convert European shoe sizes to U.S. sizes for women, use the equation shown below.US size = Euro size x 0.7882 – 22.2a) What is the mean women’s shoe size for these responses in U.S. units?b) What is the standard deviation in U.S. units?
