In order to find the interval/estimate of hours per week students study we consider the formula given below:
Interval=X±
where:
X is the mean hours
Z is the value from Z distribution table of Confidence Interval
n is the sample size of students
S is the standard deviation
X=15, Z=1.645, S=2.3hours, n=78
Interval=15±
Interval=15±0.0485
interval=(15.085,14.9515)
