Answer 1

Answer: The answer is (A) The data is skewed left and shows that on half of the days, Darren received 11 or 12 e-mails from the customer.

Step-by-step explanation: Given that Darren kept track of the number of e-mails he received from one of his customers each day for 14 days on the dot plot.

We are to select the correct statement out of the given options about the dot plot.

Since the dot plot has a long tail on the left side of the plot, so the data will be skewed left. Also, for 7 days that is half of 14 days, the number of e-mails received by Darren were 11 or 12.

Thus, the correct option is (A).
