has produced pn = .83 and we wish to test H0: p = .9 against the alternative

Question:

has produced pn = .83 and we wish to test H0: p = .9 against the alternative Ha: p 6 .9.

a. Calculate the value of the z-statistic for this test.

b. Note that the numerator of the z-statistic (pn - p0 = .83 - .90 = -.07) is the same as for Exercise 7.64. Considering this, why is the absolute value of z for this exercise larger than that calculated in Exercise 7.64?

c. Complete the test using a = .05 and interpret the result.

d. Find the observed significance level for the test and interpret its value.
