A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 296 people over the age of 55, 69 dream in black and white, and among 311 people under the age of 25, 10 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. Test the claim using a hypothesis test. 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? A. Ho: P1 P2 H₁: P1 P2 D. Ho: P₁ =P2 H₁: P1 P2 Identify the test statistic. z= B. Ho: P1 SP2 H₁: P1 P2 ○ E. Ho: P₁ *P2 H₁1: P1 P2 C. Ho: P1 P2 H₁: P1 P2 OF. Ho: P1 P2 H₁: P1 P2 (Round to two decimal places as needed.)

A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 296 people over the age of 55, 69 dream in black and white, and among 311
people under the age of 25, 10 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. Test the claim using a hypothesis test.
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?
A. Ho: P1 P2
H₁: P1 P2
D. Ho: P₁ =P2
H₁: P1 P2
Identify the test statistic.
z=
B. Ho: P1 SP2
H₁: P1 P2
○ E. Ho: P₁ *P2
H₁1: P1 P2
C. Ho: P1 P2
H₁: P1 P2
