It turns out that 51 of 80 Republicans compared to 55 of 100 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).

N B
(a) Identify the null and alternative hypotheses (1.Democrats, 2 Republicans).
A. Ho P1 =P2 against H, P, P2
OB. Ho P1=P2 against H, P1 > P2
OC. Ho P = P2 against H, pP, <P2
O D. Ho P1<P2 against H, P1=P2
O E. Ho P, # 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.)
rrect: 0
(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)
the null hypothesis because there
v significant difference between the level of support by Republican and Democrat populations The null
hypothesis is rejected for significance levels that are
than the p-value.
