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
But what does the p-value = ?

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 =?
