Ethereum is an open-sourced software system initially developed for cryptocurrency. In Computers & Security (January 2020), researchers developed a detector of malicious attacks on data traveling through the Ethereum network. Initially, the researchers used code to create a large number of normal (i.e., honest) data packets on the network. The data packets varied in size (number of bytes). Then they created code intended to maliciously attack the data packets. Samples of data packets from both the normal (160 packets) and attack (130 packets) states were collected and the variable, packet size, was determined for each packet. Minitab histograms for the two states are shown below.

a. Convert each of the frequency histograms into relative frequency histograms using the numbers shown above the bars.

b. Do you detect differences in the pattern of packet sizes for normal and attacked data packets? Explain.
