Reconsider the data from the previous study about the effect of specialized prenatal care for women with gestational diabetes. Do the data provide evidence of a relationship between the type of prenatal care a woman with gestational diabetes receives and whether or not she has an LGA baby?
a. Define (in words) the parameters of interest of this study. Also, assign symbols to the parameters.
b. State the appropriate null and alternative hypotheses in words.
c. State the null and alternative hypotheses in symbols.
d. Give detailed, step-by-step instructions on how one could conduct a tactile simulation to generate a p-value to test whether the observed difference in the conditional proportion of mothers who had LGA babies between those who received the usual prenatal care and those who received specialized care is statistically signifi cant. Be sure to include details on the following:
• Would the simulation involve coins, dice, or index cards?
• How many tosses, rolls, or cards would be used?
• How many sets of tosses, rolls, or shuffles would you observe?
• What would you record aft er every repetition?
• How would you compute the p-value?

Data from previous question

A baby weighing more than 4,000 g at birth is considered to be large for gestational age (LGA). Gestational diabetes in the mother is believed to be a common risk factor for LGA. In an article published in the New England Journal of Medicine (October 2009), researchers Landon et al. reported a study of 958 women diagnosed with mild gestational diabetes between 24 and 31 weeks of pregnancy who volunteered to participate in the study and then were randomly assigned to one of two groups: 473 to usual prenatal care (control group) and 485 to dietary intervention, self- monitoring of blood glucose, and insulin therapy, if necessary (treatment group). Of the 473 women in the control group, 68 had babies who were LGA, and of the 485 women in the treatment group, 29had babies who were LGA.
