A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 317 people over the age of 55, 69 dream in black and white, and among 296 people under the age of 25, 15 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.

Question
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among
317
people over the age of 55,
69
dream in black and white, and among
296
people under the age of 25,
15
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.

Transcribed Image Text:Identify the test statistic.
z=
(Round to two decimal places as needed.)
Identify the P-value.
P-value = 0.000
(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
evidence to support the claim that the proportion of people over 55 who dream in black and white is greater than the
proportion for th
less than
An explanation
hose over the age of 55 grew up exposed to media that was displayed in black and white. Can these results be used to verify that explanation?
greater than
O A. No. The
ssible difference between the proportions of people over 55 and under 25 who dream in black and white, but the results cannot be used to verify the cause of such a difference.
O B. Yes. The results can be used to verify the given explanation because the difference in proportions is practically significant.
O C. Yes. The results can be used to verify the given explanation because the difference in proportions is statistically significant.
O D. No. The results speak to a possible difference between the proportions of people over 55 and under 25 who dream in black and white, but the results are not statistically significant enough to verify the cause of such a difference.
