An article published in the Washington Post claims that 45
percent of all Americans have brown eyes. A random sample of
?=76n=76 college students students found 28 who had brown
eyes.
Consider testing:
?0:?=.45
??:?≠.45
a) the test statistic is z = ?
b)P-value = ?

An article in the Washington Post on March 16, 1993 stated that nearly 45 percent of all Americans have brown eyes. A random sample of n=82 n=82 C of I students found 30 with brown eyes. We test H 0 :p=.45 H0:p=.45 H a :p≠.45 Ha:p≠.45 (a) What is the z z -statistic for this test? (b) What is the P-value of the test? please show what functions and steps you take , thank you

Hypothesis Testing- Problem (3): Problem (3): An article in the Washington Post on March 16, 1993 stated that nearly 45 percent of all Americans have brown eyes. A random sample of n - 82 UNG students found 30 with brown eyes. Suppose p is the true proportion of those who have brown eyes. Does this sample provide evidence at the 5 percent level that the proportion of brown eyes is different than the 45% proportion stated in 1993? Preparation Step:...
(1 pt) A random sample of n = 80 students found 40 with brown eyes. Give the numerical value of the statistic , the sample proportion who have brown eyes
ne Sample Hypothesis Tests: Problem 7 Previous Problem List Next (1 point) An article in the Washington Post stated that nearty 45 percent of all Americans take a daily medication. A random sample of n -82 people in Georgia found 30 who take a daily medication. Use this information to test the hypotheses Ho : p = .45 where p represents the population proportion of Georgians who take a daily medication. (a) What is the value of the sample proportion...
According to an article, the average non-mortgage debt of Americans is $23800. A simple random sample of 60 Americans was selected, and their average non mortgage debt was found to be $22500. Assume the population standard deviation of non-mortgage debt is $4600. Is there sufficient evidence to conclude that the average non-mortgage debt of Americans has decreased? Use α = 0.05. a) State the null and alternative hypotheses in the context of the question. b) Calculate the value of the...
The Washington Post reported that 80% of all high school students had computers at their home. A random sample of 500 high school students in an urban area is taken, and it reveals that 425 students have computers at home. Test if the proportion of high school students in this urban area who have computers at their home exceeds 80%. Use a 0.1 level of significance. Part A: State the null and alternative hypotheses. a. H0: p = 0.8, Ha:...
Hypothesis Testing - Setup: The American Mathematical Association claims that less than 40% of all Americans like statistics. In a random sample of 80 Americans, 37% of them liked mathematics. Suppose you were to test the claim of the American Mathematical Society. (a) What is the claim? p < 0.40 p > 0.40 p = 0.40 p < 40 (b) What does p represent? the mean number of Americans who like statistics the proportion of all people in the sample...
