How to Make a scatterplot of weight versus desired weight. Describe the relationship between these two variables.

plot( cdc$weight , cdc$wtdesire)

#. Let's consider a new variable: the difference between desired weight (wtdesire) and current weight (weight).

# if a new variable by subtracting the two columns in the data frame and assigning them to a new object called wdiff.

wdiff = cdc$wtdesire - cdc$weight

#. What type of data is wdiff? If an observation wdiff is 0, what does this mean about the person's weight and desired weight.

#What if wdiff is positive or negative?

#. Describe the distribution of wdiff in terms of its center, shape, and spread, including any plots you use.

#What does this tell us about how people feel about their current weight?

#. Usingdmumerical summaries and a side-by-side box plot, determine if men tend to view their weight differently than women.

#. Now it's time to get creative. Find the mean and standard deviation of weight and determine

#what proportion of the weights are within one standard deviation of the mean.
