Question

In Texas, the average hot dog eating contest winner eats 46 of the 60 provided hotdogs. If you give a sample mean of 38 with a standard deviation of 3.5 where 25 contestants attempted the event, what will be the z value and p score?

Ho: µ>=46

Ha: µ<38

You can put this in excel or your calculator

= (46-38)/(3.5/25^.5)

= 11.42

if α=.05, 1 tailed test and z= 11.42, you get the answer for

(a) p=

(b) Do you reject or not reject the null
