Question: Let a=5, b=4, c=9 . For example, suppose a random sample of university students is selected to determine a difference between male and female students

Let a=5, b=4, c=9. For example, suppose a random sample of university students is selected to determine a difference between male and female students rest time. Let a³male students are randomly chosen and obtained an average of (a+b)² hours of rest with a standard deviation of 1.8. Similarly a random sample of b² female students are randomly selected with an average of (a+b) hours of rest with a standard deviation of 1.5.

Construct a95% confidence intervalfor the difference between two means rest time for males and females.
