The demand function for good X is QXd $=$ a $+$ bPX $+$ cM $+$ e$,$ where Px is the price of good X and M is income. Least squares regression reveals that:

a$=8\mathrm{.}27$ b$=2\mathrm{.}14$ c$=0\mathrm{.}36\backslash$sigma a$=5\mathrm{.}32\backslash$sigma b$=0\mathrm{.}41\backslash$sigma c$=0\mathrm{.}22$

The R$-$squared is $0\mathrm{.}35.$

a$.$ Compute the t$-$statistic for each of the estimated coefficients.
