$(6b-6)(-12)=(-4)(3b+27)$
$-12(6b-6)=-4(3b+27)$
$-72b+72=-12b-108$
$-72b=-12b-180$
$-60b=-180$
$b=3$

The average weekly earnings in the leisure and hospitality industry group for a re‐ cent year was $273. A random sample of 40 workers showed weekly average ear‐ nings of $285 with the population standard deviation equal to 58. At the 0.05 level of significance can it be concluded that the mean differs from $273? Find a 95% con‐ fidence interval for the weekly earnings and show that it supports the results of the hypothesis test.
