![A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches.
**Find the 90% confidence interval for the mean height of all female students in their school.**
Assume that the distribution of individual female heights at this school is approximately normal.
1. The t value is \(1.3025\).
2. The standard error has a value of \([dropdown menu]\).
3. The margin of error has a value of \([dropdown menu]\).
4. Find the 90% confidence interval for the mean height of all female students in their school \(( \_ , \_ )\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8592f3b3-859c-46ab-b392-3c205ebbc3fb%2Fd4ec379f-6c9e-49c6-a307-0d6d83c0995b%2F47ba1r9_processed.jpeg&w=3840&q=75)
