Assume the hourly wage rate for a fast-growing online job is normally distributed with a mean of u = $23.40. Suppose a random sample of n = 27 workers revealed a mean wage of 5: = $24.07 and a standard deviation of s = $1.34. At a = 0.2, is there enough evidence to conclude that the mean hourly wage is different from $23.40? a. Select the appropriate alternative hypothesis, H1 or Ha: on > $23.40 on > $24.07 Op 94 $24.07 0,4 74 $23.40 OH
