Let be the population proportion of employed individuals who work at home at least once per week.
The sample size is n = 400
Total number of employed individuals who work at home at least once per week is : x = 25
The proportion is given as
= 0.0625
The confidence interval is given
is critical z score
= 2.58
The lower bound is given
=
= 0.03127407
Rounding to three decimal places
= 0.0312
The upper bound is given as
=
= 0.09372593
Rounding to three decimal places
= 0.0937
Therefore the 99% confidence interval is given as
[ 0.0312 , 0.0937]
