A random sample of 57 employees shows their average salary to be $29,500 with a population standard deviation of $1200. Test the hypothesis using a 3% level of significance. Using either the classical approach or the P-value approach: (Step 5) Decision: O There is not sufficient evidence at the 0.03 level of significance to show the mean salary at FleetFoot Shoe Company is less than $29,800. There is sufficient evidence at the 0.03 level of significance to show the mean salary at FleetFoot Shoe Company is less than $29,500. O There is sufficient evidence at the 0.03 level of significance to show the mean salary at FleetFoot Shoe Company is less than $29,800. There is not sufficient evidence at the 0.03 level of significance to show the mean salary at FleetFoot Shoe Company is less than $29,500.
