Lab 8-Hypothesis For each hypothesis test, you must include the following: ● Identification of the appropriate test to use Null and alternative hypothesis with a labeled claim Test Statistic · . ● ● Testing (One Sample) . ● P-Value A sketch of the critical region(s) with the test statistic clearly labeled Justification for rejecting or failing to reject the null hypothesis A complete sentence conclusion which includes the original claim. Part 1. Proportion 1. According to the Washington Post, nearly 45% of all Americans are born with brown eyes, although their eyes don't necessarily stay brown. A random sample of 80 adults found 32 with brown eyes. Is there sufficient evidence (at the 0.01 significance level) to indicate that the proportion of brown-eyed adults differs from the proportion of Americans who are born with brown eyes?

O O Lab 8-Hypothesis Testing (One Sample) For each hypothesis test, you must include the following: Identification of the appropriate test to use Null and alternative hypothesis with a labeled claim Test Statistic 8 . P-Value A sketch of the critical region(s) with the test statistic clearly labeled Justification for rejecting or failing to reject the null hypothesis A complete sentence conclusion which includes the original claim. Part 1. Proportion 1. According to the Washington Post, nearly 45% of all Americans are born with brown eyes, although their eyes don't necessarily stay brown. A random sample of 80 adults found 32 with brown eyes. Is there sufficient evidence (at the 0.01 significance level) to indicate that the proportion of brown-eyed adults differs from the proportion of Americans who are born with brown eyes? 2. A manufacturer of automatic washers offers a model in one of three colors: A, B, or C. Of the first 1000 washers sold, 400 were of color A. Would you conclude that customers have a preference for color A? Justify your answer. Assume that "the first 1000 washers sold" is a random sample. 3. In March 2001, a Gallup poll asked, "How would you rate the overall quality of the environment in this country today-as excellent, good, fair or poor?" Of 1060 adults nationwide, 46% gave a rating of excellent or good. Is this convincing evidence that a majority of the nation's adults think the quality of the environment is fair or poor? Test using a = .05. SEP
