Use the 'PLUC' dataset and refer to the description provided on CANVAS. Conduct a two$-$sample independent t$-$test to determine if the population mean height of males is different from that of females. Calculate the p$-$value.

Hint:

hgt$.$m $=$ hgt$[$sex$=="$m$"]$

hgt$.$f $=$ hgt$[$sex$=="$f$"]$
