Transcribed Image Text:It turns out that 83 of 125 Republicans compared to 56 of 125 Democrats in the Congress are supporting a trillion-dollar rescue package to for the economy. Help analysts understand whether there is a significant difference between the opinions of Republican and Democrat populations against the rescue package (assuming
that they can tolerate 5% Type I error).

(a) Identify the null and alternative hypotheses (1:Democrats, 2:Republicans).
O A. Ho: P1= P2 against H,: p, # p2
O B. Ho: P1 = P2 against H,: P <P2
OC. Họ: P1 = P2 against H1: P1 > P2
O D. Ho: P1 < P2 against H,: P1 = P2
O E. Ho: P1 # p2 against H,: P1 =P2
O F. Ho: P1> P2 against H,: P1 = P2
(b) The z value can be computed as (Round to two decimal places including any zeros.)
(c) The p-value is the total tail probability corresponding to the calculated test value, which is then compared to a. In a two-tailed test, this is 2P(Z> z) (assuming z> 0) or, in a right-tailed test, this is P(Z>z).
The p-value of the test can be computed as
(Round to four decimal places including any zeros.)
(d)
V the null hypothesis because there
significant difference between the level of support by Republican and Democrat populations. The null hypothesis is rejected for significance levels that are
V than the p-value.
