According to the U.S. Census Bureau, 69% of children under the age of 18 years in the United States lived with two parents in 2009. Suppose that in a recent sample of 1925 children, 1215 were living with two parents.
a. Using the critical value approach and significance level=0.02, test whether the current percentage of all children under the age of 18 years in the United States who live with two parents is different from 69%.
Enter the critical values in increasing order. Round your answer for z to two decimal places.
OBSERVED Z=?
CRITICAL VALUE=?
b. What is the probability of making a type one error from part a?
P(TYPE ONE ERROR)=?
c. Calculate the p-value for the test from part a.
P-VALUE=?

The publisher reports that 80% of college professors require or recommend that their students purchase some type of textbook package.
Conduct the test and state your conclusion. Use α = 0.05. Does the choice of level of significance change your conclusion? Explain.
The design should include two factors that you think influence the response, such as location, age, income, or education. Each factor should have three levels for testing in the model.
Assuming that the samples come from a normal distribution: Test that the mean SAT score for math in 1999 is greater than that in 1989 at α = 0.05. Assume the variances are equal.
how many individuals will I need to sample if I want a 95% margin of error to be no more than 3%, I want to know if the results are significant at = 10%. With the information given.
Birth weights of babies in the United States can be modeled by a normal distribution with mean 3250 grams (7.165 pounds) and standard deviation 550 grams (1.213 pounds). Those weighing less than 2500 grams (5.512 pounds) are considered to be l..
Calculate the test statistic and Find expected frequencies - Identify the claim and state the null and alternative hypotheses and determine the degree of freedom, find the critical value, and identify the rejection region.
Illustrate what does weighting add to usefulness of moving averages and explain how is it done. The yield on a thirty year treasury note at the end of every year since 1990 is recorded below.
What is the probability that the cereal would be high fiber? In other words, what is P (high fiber)?
