Question
-a system that takes 4.5 years, on average, to finish
-suppose you believe that the
-you conduct a survey of 40 students
-a sample mean of 5.1 w/ a sample standard deviation of 1.2.
-claim at the 1% level?
null hypothesis is : Ho: µ≤4.5
alternative hypothesis is: Ha: µ > 4.5
the test statist is: t = 3.175
p-value = .0015
The main trouble I’m having is labeling the lower bound and upper bounds for a 95% confidence interval for the true mean.
The point estimate= 5.1
Lower bound=?
Upper bound =?
