A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 314 people over the age of 55, 62 dream in black and white, and among 282 people under the age of 25, 15 dream in black and white. Use a 0.01 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? OB. Ho: P1 = P2 O C. Ho: P1 =P2 H: P1 #P2 O A. Ho: P1 SP2 H:P1 #P2 H1:P1> P2 OD. Ho: P1 = P2 O E. Ho: P1 2P2 H1: P1 #P2 O F.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
