Question
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among
317317
people over the age of 55,
7070
dream in black and white, and among
296296
people under the age of 25,
1515
dream in black and white. Use a
0.050.05
significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts (a) through (c) below.a. Test the claim using a hypothesis test.
Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test?

Upper H 1H1:
p 1p1not equals≠p 2p2
Upper H 0H0:
p 1p1equals=p 2p2
Upper H 1H1:
p 1p1less than<p 2p2
Upper H 0H0:
p 1p1less than or equals≤p 2p2
Upper H 1H1:
p 1p1not equals≠p 2p2
Upper H 0H0:
p 1p1not equals≠p 2p2
Upper H 1H1:
