A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 295 people over the age of 55, 62 dream in black and white, and among 292 people under the age of 25, 13 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.

![A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 295 people over the age of 55, 62 dream in black and white, and among 292
people under the age of 25, 13 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.

The P-value is less than the significance level of a = 0.05, so reject the null hypothesis. There is sufficient 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43a88bb5-68f0-4994-862d-8655793efb49%2F23027601-49e8-439e-b98c-c6306272cf99%2Fn1lsn1d_processed.jpeg&w=3840&q=75)
