Suppose we wanted to estimate the mean number of hours that all PACollege students spend on their Math260 homework. We don't know the actual mean, but from the previous studies, we have concluded that the standard deviation of all students is 3.2 hours. A sample of 32 students found that average numbers spent on homework was 10.4. Question: Create a 90% confidence interval to estimate for all students at PACollege.

Suppose we wanted to estimate the mean number of hours that all PACollege students spend on
their MAT260 homework. We don't know the actual mean, but from the previous studies, we have
concluded that the standard deviation of all students is 3.2 hours. A sample of 32 students found
that the average number of hours spent on homework was 10.4. (Choose only 1 question to

1. Create a 90% confidence interval to estimate the average for all students at PACollege.
Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
