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. Use an appropriate randomization-based applet to nd 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 significant. Report and interpret the p-value in the context of the study.
b. Based on this p-value, how much evidence do you have against the null hypothesis?
c. Calculate an appropriate standardized statistic and interpret the standardized statistic in the context of the study.
d. Do the p-value and standardized statistic both lead you to the same conclusion?
e. Use the 2SD method to find a 95% confidence interval for the parameter of interest. Report this interval and interpret the interval in the context of the study.
f. Is your conclusion from using either the p-value or the standardized statistic consistent with your finding from the 95% confidence interval? How are you deciding?
g. State a complete conclusion about this study, including significance, estimation (confidence interval), causation, and generalization. Be sure to explain how you are arriving at your conclusion.
