Use the one-proportion z-test to perform the specified hypothesis test. Use the critical-value approach.

x = 741, n = 1300, H0: p ≤ 0.5, Ha: p > 0.5, α = 0.05

a) z = 5.048; critical value = 1.645; reject H0

b) z = 3.786; critical value = 1.645; reject H0

c) z = 3.786; critical value = 1.96; do not reject H0

d) z = 5.048; critical value = 1.96; reject H0
