Answer: p-value= 0.5686
Explanation:
11% = 11/100 = 0.11
Null hypothesis is p = 0.11
Alternative hypothesis is p ≠ 0.11
Therefore, this test is a two tailed test.
Given,
Null parameter, P,= 0.11
Sample Statistics, Phat, = 8/88 = 1/11
= 0.09091
n = 88
z= (sample statistics - Null parameter) ÷ SE
z = (phat - p)/√[p(1-p)/n]
z = (0.09091 - 0.11)/ √[0.11(1-0.11)/88]
z = - 0.019091 ÷ √0.0011125
z = - 0.019091 ÷ 0.033354
z = - 0.572375
Z ≈ - 0.57
According to the table
z = -0.57 = 0.2843
Since it's a two tailed test,
Therefore,
p value = 2 x 0.2843 = 0.5686
