A study of iron deficiency among infants compared blood hemoglobin levels of a random sample of infants who had been breast-fed to a random sample of infants who had been fed with standard infant formula. Here are the results. Breast-fed infants Formula-fed infants 23 19 13.3 1.7 12.4 1.8 We want to test H, :H3 - H; = 0, H,i-Hg#0, where lz and H; are the population mean blood hemoglobin levels for breast-fed and formula-fed infants, respectively. (a) What additional information would you need to confirm that the conditions for this test have been met? (b) Assume the conditions have been met. Calculate the standardized test statistic and P-value for this test. (C) What conclusion would you make at the a = 0.05 significance level? (d) Given your conclusion in part (c), which type of error, Type I or Type II, could you have made? Describe that error in the context of this study.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
