According to an economic organization, the weekly hours worked in manufacturing in a country was 42 hours in 2017. A recent random sample of 70 manufacturing workers in this country was selected, and it was found that they worked an average of 38.8 hours last week with a sample standard deviation of 10.7 hours. a. Using a = 0.10, is there enough evidence from this sample to conclude that the average number of manufacturing hours worked per week is different than 42 hours? b. Determine the precise p-value for this test using Excel. According to an economic organization, the weekly hours worked in manufacturing in a country was 42 hours in 2017.
