The pie chart shows the distribution of the opinions of parents on whether a college education is worth the expense. An economist claims that the distribution of the opinions of teenagers is different from the distribution for parents. To test this claim, you randomly select 197 teenagers and ask each whether a college education is worth the expense. Strongly agree The table to the right shows the results. At a = 0.05, test the economist's claim. Click the icon for the pie chart of the distribution. Response Somewhat agree Neither agree nor disagree Somewhat disagree Strongly disagree Survey results State Ho and H₂ and identify the claim. Ho: The distribution of the opinions of whether a college education is worth the expense is the same for teenagers and parents. Ha: The distribution of the opinions of whether a college education is worth the expense is different for teenagers and parents. Which hypothesis is the claim?

Suppose you know the population mean and are interested in seeing how a sample average compares to this mean. You take some samples of size 10 and other samples of size 35. How will the sampling distribution of the means be different for the larger size samples compared to the sampling distribution of the means for the smaller size samples?

Nurses wondered if birth weights of babies are going up. They knew that the average birth weight of a baby last year was 7.6 pounds. A random sample of 15 weights of babies at the hospital where the nurses work gave an average birth weight of 7.9 pounds. Nurses felt that the birth weights this year were normally distributed. Which of the following is true about the distribution of sample means? Choose the correct answer below. O A. Even though the sample size is less than 30, the distribution of sample means will be normal because the population data follow a normal distribution. OB. The distribution of sample means will be normal regardless of the shape of the data in the population. Oc. Since the sample size is less than 30, the population data cannot be normally distributed. Therefore, the distribution of sample means will not be normally distributed. D. The distribution of sample means will not be normal even though the population data followed a normal distribution because the…
