You suspect that men in town A weigh, on average, more than men in town B, You decide to carry out a study. Suppose the following are the weights (in pounds) of a random sample of men in these two towns (Please show using R studio):

A 195.0 200.0 209.0 198.0 200.5 207.5 199.0 205.0 220.0

B 192.0 183.0 194.5 185.0 214.0 203.5 194.0 199.0 109.0

(a) First, create exploratory plots of the data in the two towns. What do you observe?

(b) Carry out a hypothesis test. Is there evidence that men in town A weigh more, on average, than men in town B?

(c) There is an outlier in one of the towns. Remove this observation and repeat the test. Is this outlier influential?
