( 26.66 , 32.94)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given random sample size 'n' = 20

Standard deviation of the sample (S) = 6.7
Given Margin of error = 3.14
<u><em>Step(ii):</em></u>-
95% confidence interval for the mean is determined by

We know that margin of error is determined by

Now 95% confidence interval for the mean time spent on housework per week by all married women.

( 26.66 , 32.94)
