A study wаs cоnducted tо identify likely cаndidаtes fоr fetal alcohol syndrome. In order to find out the effect of the alcohol, the effect of mother’s weight should be separated out first. Therefore, the relationship between mother’s weight and infant’s birthweight should be specified. In other words, we need to figure out what the baby should weigh based on the mother’s weight. We have the data from 25 cases with mother’s weight in kilograms and the infant’s birthweight in grams. We conduct a linear regression to specify this relationship. The summary output is provided below. Fill in the missing elements in the table, labeled with letters (e), (f), (g), (h). Write your answers in the space below, showing your work. (Partial credit is available). You may leave answers as fractions if you do not have a calculator. (f) [SStotal] (e) [R_square] (h) Construct a 95% confidence interval for the slope of this linear regression. A t distribution with 23 degrees of freedom has percentile . (Filling in the confidence interval formula is good enough) [CI_slope] (g) Will the p-value be >0.05 or

Correlation Multiple Linear Regression ANOVA Two Sample T-test a) An alternative way to measure severity of diarrheal disease is to measure the total number of days for which the child experienced diarrheal illness. Which method should they use to test if these two measures of diarrheal illness (number of episodes of diarrhea and the total number of days for which the child experienced diarrhea) are significantly linearly related? [which_test_1] b) The number of family members in the household, type of toilet, and annual household income are associated with the number of episodes of diarrheal illness experienced by children under five years old. Which method should they use to model the predicted number of episodes of diarrheal disease for children under 5 years old with a given number of family members, type of toilet, and annual household income? [which_test_2] c) Which method should they use to test whether the mean number of episodes of diarrheal disease is the same for children from households using a private toilet vs. children from households using a pit toilet vs. children from households using open defecation? [which_test_3] d) India uses the caste system, in which the population is divided into different groups. Which method should they use to test whether the mean number of episodes of diarrheal illness is equal for children in the scheduled caste (“untouchables”) when compared to children not in the scheduled caste?
