-a system that takes  4.5 years, on average, to finish

-suppose you believe that the mean time is longer.

-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

But what does the p-value = ?

-suppose you believe that the mean time is longer.

-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 = 0.0015

Point estiment= 5.1

for a graph of the situation with a 95% confidence interval for the true mean what does the lower bound=? And the upper bound =?
