A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 298 people over the age of 55, 62 dream in black and white, and among 282 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) Determine the hypothesis, Test statistic, and P-value 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 these results be used to verify that explanation? Use this information to determine whether the results can be used to verify the black and white media explanation.
