a. .8
Step-by-step explanation:
The point estimate of the difference between the means of Company 1 and Company 2 can be calculated as:
point estimate = mu1 - mu2 where
mu1 is the sample mean hourly wage of Company 1mu2 is the sample mean hourly wage of Company 2Therefore point estimate = $10.80- $10 =$ .8
