A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 303 people over the age of55, 60 dream in black and white, and among 312 people under the age of 25, 15 dream in black and white. Use a 0.01 significance level to testthe 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?O A.

A publisher reports that 52 % of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 350 found that 46 % of the readers owned a laptop. State the null and alternative hypotheses.
According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value
