In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1=not attractive; 10=extremely attractive). Construct a confidence interval using a 99%confidence level. What do the results tell about the mean attractiveness ratings of the population of all adult females? 5,8,3,8,5,5,6,7,9,8,6,9 What is the confidence interval for the population mean μ?

Construct a confidence interval using a 99%confidence level. What do the results tell about the mean attractiveness ratings of the population of all adult females?
5,8,3,8,5,5,6,7,9,8,6,9
What is the confidence interval for the population mean μ?
Expert Solution
Step 1
Obtain the 99% confidence interval for the population mean μ.
The 99% confidence interval for the population mean μ is obtained below as follows:
The formula for the Confidence interval for mean is:
Use EXCEL Procedure to obtain values for the given samples.
Follow the instruction to obtain the value of mean and SD:
- Open EXCEL
- Go to Data>Data Analysis.
- Choose Descriptive Statistics.
- Enter the input range as $A$1:$A$13.
- Check the Labels in the first row.
- Check the option Summary statistics
- Click OK.
EXCEL output:
From the EXCEL output, the value of mean is 6.5833 and the standard deviation is 1.8809
