You need to decide which of two brands of chocolate chip cookies to buy. You really love chocolate chip cookies. The numbers of chocolate chips in each of five cookies from each brand are as follows:

Draw a dot plot for each set of data that shows the distribution of number of chips for each brand. Use a scale for your dot plots that covers the same span for both distributions.

Find the mean number of chocolate chips for each of the two brands. Compare the means.
