Anewspaper conducted a statewide survey concerning the 1998 race for state senator. the newspaper took a srs of n=1400 registered voters and found that 720 would vote for the republican candidate. let p represent the proportion of registered voters in the state who would vote for the republican candidate.
we test

h0: p=.50
ha: p> .50

(a) what is the z -statistic for this test?

(b) what is the p-value of the test?

a) 1.07, b) 0.1423

Step-by-step explanation:

Since we have given that

n = 1400

Number of voters vote for Republican candidates = 720

So,

And hypothesis are :

(a) What is the z -statistic for this test?

(b) What is the P-value of the test?

p-value = P(Z>Z(statistics))

Hence, a) 1.07, b) 0.1423

step-by-step explanation:

where is the question is there is a formula or is there not one

130 degrees. i have no other way to explain
