According to a World Health Organization (WHO) report, the global prevalence of anemia among pregnant women is 40%. You suspect that it might be higher for one particular district. Conducting a test of significance (or = 0.05) with the hypotheses Ho: p s 0.4 vs Ha: p > 0.4, you failed to reject the null hypothesis. If the true percentage of anemia in pregnant women in the district is 61%, did an error occur? If so, what type of error is it? [$0urce: Toteja, G. 5., Singh, R, Dhillon, B. 5., Saxena, B.

You decide to test this claim, so you decide to perform a test of significance on this as you analyze the difference in length of the left and right feet (Left-Right) for 25 people. Which of the following pairs of hypotheses would be appropriate?

To estimate this, you recorded data from the two hospitals of patients diagnosed with foodborne disease and admitted for observation for at least one night. The data you collected is summarized below: Hospitals Sample size (n) .53 Conduct a test of significance at a = 5% with the hypotheses Ho: p1 p2 = 0 and Ha: p1 _ p2 at 0. The p-value will be ______
