What is the mean, median, standard deviation, and IQR of the following variables: length, birthweight, motherage, headcircumference, and gestation. In a couple sentences, briefly describe the descriptive statistics you calculated.

Research Question: Is there a correlation between gestation and babies birth weight?
a. What type of statistical test do you need to conduct to answer this research question?
c. Use excel to create a scatterplot to show the association between gestation and birthweight. On the plot, include a linear trendline and the regression formula.
d. Conduct the appropriate statistical analysis in JAMOVI to determine if there is a correlation between gestation and babies birth weight. Report your findings in a sentence.
e. If a baby is born at 36 weeks gestation, what would their predicted birthweight be based on the regression formula? Provide the error (95%) for this birthweight estimated.
