Question
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 309 people over the age of 55, 77 dream in black and white, and among 309 people under
the age of 25, 18 dream in black and white. Use a U.U5 signiticance 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.
Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the
hypothesis test?
Identify the test statistic.

What is the conclusion based on the hypothesis test?
The P-value is ______ the significance level of a = 0.05, so ______ black and white is ____
the proportion for those under 25. There is ____ to evidence to support the claim that the proportion of people over 55 who dream in
