An important factor in selling a residential property is the number of people who look through the home. A sample of 14 homes recently sold in the Buffalo, New York, area revealed the mean number looking through each home was 25 and the standard deviation of the sample was 6 people.

Develop a 95% confidence interval for the population mean. (Use *t* Distribution Table.) **(Round your answers to 2 decimal places.)**

confidence interval for the population mean is between _____ and ________

Step 1

Given information:

Sample size (n) = 14

Sample mean=25

Sample standard deviation=6

Step 2

Confidence level=95%

So,

Significance level=1- Confidence level

=1-95%

=1-0.95

=0.05

Degree of freedom=n-1

=14-1

=13

Step 3

Using t-table, the value of t-critical at 0.05 significance levels and 13 degre...
