the proportion for those under 25. A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 325 people over the age of 55, 65 dream in black and white, and among 313 people under the age of 25, 12 dream in black and white. Use a 0.01 significance level to test the cla im 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. CaivD) What is the conclusion based on the hypothesis test? The P-value is the significance level of o = 0.01, so lj the null hypothesis. There is evidence to support the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. k b. Test the claim by constructing an appropriate confidence interval. The 98% confidence interval is D
