Question

Problem 6 [Avec R] Download the 'heightweight.csv' dataset from CANVAS. This contains 25000 entries of height and weight from some sample of the population after a survey. (a). Draw a histogram for both height and weight using R (b). Draw a smoothed histogram for both height and weight using R. The function density' will help (c). Draw a scatter plot for height and weight. (d). Say your friend Bill was frustrated with his short stature and would like to grow taller. Would gaining weight be a good way to achieve that goal based on this data (and logic!)?

Answer 1

As data set was not avaiable but can use following code to solve this problem"

R coding

read.csv(file = 'data/heightweight.csv', header = FALSE)

hist(height)
hist(weight)
scatter.smooth(height,weight)

conclusion: if scatter plot have positive slope in upward direction, this implies there s positive relation between height and weight, which means increase in weight implies increase in height from given data.
