Answer:
Yes, the mean number is more than 40
Step-by-step explanation:
The null hypothesis
H0 = mean is 40
Let´s make the t test
t = (x – mean) / standard deviation / √sample size
t = (42 – 40) / 2.1 / √28
t = 5.039
now we find t value for one tail, using a T-distribution table
df = n – 1 = 27
α = 0.05
so, t = 1.703
since our calculated t value is greater than the t for the table, the null hypothesis can be rejected. So the mean number of calls per salesperson per week is more than 40.
