In order to determine whether or not there is a significant difference between the hourly wages of two companies, the following data have been accumulated

Company $1$

Company $2$

$n_1=90$

$n_2=70$

${\stackrel{}{x}}_2=$$$12\mathrm{.}00$

${}_2=$$$1\mathrm{.}40$

${\stackrel{}{x}}_1=$$$12\mathrm{.}50$

${}_1=$$$2\mathrm{.}00$

The $p-$value is

a$.0\mathrm{.}0632$

b$.0\mathrm{.}4684$

c$.0\mathrm{.}0316$

d$.0\mathrm{.}9368$
