A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 306 people over the age of 55, 68 dream in black and white, and among 298 people under the age of 25, 13 dream in black and white (based on data from "Do We Dream in Color?" by Eva Murzyn, Consciousness and Cognition, Vol. 17, No. 4). We want to 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 of those under 25. 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 me- dia that was mostly displayed in black and white. Can the results from parts (a) and (b) be used to verify that explanation? A study was conducted to determine the proportion of people who dream in black and white instead of color.
