Below is data on the length and weight of a sample of 10 low birth weight infants (Table B.23 in the textbook): Length (cm) Weight (g) 32 880 39 1130 38 1140 39 1350 37 950 39 1220 38 980 42 1480 39 1250 38 1250 (a) (Not marked.) Enter the data as two vectors in R. Then, save them to a single dataframe. (b) Use R to create a scatterplot of the data, with weight as the response variable. (c) Use R to calculate the correlation between the two variables. What does this value tell us about the relationship between length and weight of low birth weight infants? (d) What is the correlation between length and weight, when weight is measured in kilograms (instead of grams)? Show your work, or explain your reasoning
