Consider the computer output below

Using the normal approximation:

(a) Fill in the missing information.

(b) What are your conclusions if α = 0.05?

(c) The normal approximation to the binomial was used here. Was that appropriate?

(d) Find a 95% upper-confidence bound on the true proportion.

(e) What are the P-value and your conclusions if the alternative hypothesis is H₁: p ‰  0.25?
