Answer:
There is evidence to prove that mean is less than 60 hours.
Step-by-step explanation:
Given that the mean work week for engineers in a start-up company is believed to be about 60 hours.
Sample size taken = 10
(left tailed test )
Data (length of mean work week): 70; 45; 55; 60; 65; 55; 55; 60; 50; 55.
Mean difference = -3
Test statistic t =mean differene/std error
= -20.72
p value <0.00001
Since p < 0.05 at 5% level we reject H0
There is evidence to prove that mean is less than 60 hours.
