A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 293 people over the age of 55, 60 dream in black and white, and among 289 people under the age of 25, 20 dream in black and white. Use a 0.01 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.(b) Test the claim by constructing an appropriate confidence interval.(c) An explanation given for the results is that those over the age of 55 grew up exposed to media that was mostly displayed in black and white. Can the results from part (a) and (b) be used to verify that explanation?
