A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 305 people over the age of 55, 80 dream in black and white, and among 305 people under the age of 25, 18 dream in black and white. Use a 0.05 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. (Round to two decimal places as needed.) Identify the P-value. P-value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? The P-value is the significance level of a = 0.05, so v the null hypothesis. There is V evidence support the claim that the proportion of people over 55 who dream black and white greater than the proportion for those under 25 b. Test the claim by constructing an appropriate confidence interval. The 90% confidence interval is < (P1 -P2)

Question
please help solve attached
the p value is less than or greater than the significance level of
α=0.05, so reject or fail to reject the null hypothesis There is
sufficient or insufficient 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.
What is the conclusion based on the confidence interval? Because the confidence interval limits include or do not include
0, it appears that the two proportions are equal or not equal.
Because the confidence interval limits include only negativeor
Because the confidence interval limits include only negativeor
only positive or
positive and negative values, it appears that the proportion of people over 55 who dream in black and white is lesser than greater than not significantly different from the proportion for those under 25.
