Data on claim amounts for central heating insurance were collected from a large portfolio of an energy company. The amounts (£) of a sample of 24 claims were as follows. 200, 201, 201, 202, 209, 211, 215, 218, 228, 228, 235, 238, 262, 265, 269, 270, 314, 316, 320, 339, 345, 349, 351, 464. Note that for this sample of data, Ex = 6450 and Ex² = 1838620. Calculate the mean and standard deviation of the insurance claim amounts. Draw a stem-and-leaf plot of the data and comment on the shape of the distribution.
