The bloodhound is the mascot of John Jay College. Suppose weweigh n=8 randomly selected bloodhounds and get the followingweights in pounds
85.6, 91.6, 105.9, 83.1, 102.1, 92.5, 108.8, 81.4
Assume bloodhound weight are normally distributed with unknown meanof μ pounds and an unknown standard deviation ofσ pounds.
e) Suppose W has a t distribution with 7 degrees of freedom. IfP(W > t) = .03 then what is t? Â
f) Suppose W has a t distribution with 7 degrees of freedom. If P(W< t) = .03 then what is t? Â
g) Calculate the 97th percentile of a standard normaldistribution. Â
h) Compute a 94% Confidence Interval for μ using youranswers above.
i) Compute a 94% Prediction Interval for a single futurebloodhound weight measurement using your answers above..
