Professor Chauvet wanted to know how quickly her students can type out a text message. So that everyone typed the same thing, she asked the students to type (and send!) the alphabet to someone in a text message. She gave them 15 seconds and asked them to type out as much of the alphabet as possible in that time frame. (Each letter needed to be followed by a space before the next letter was typed.) When time was up, the students pressed send. Then they counted how many characters they typed. Here is a stemplot of the results: Note that the students who only typed 4 and 7 characters claimed to have issues with autocorrect on their phones. Here is a stemplot of the results: 0 47 1 389 2 0444555667779 3 4 01278999 5 2 0000112234566666888 512 represents a student who typed the entire alphabet in the 15 allotted seconds. Which of the following correctly displays these data in the form of a histogram? Frequency Frequency Frequency Frequency 10₁ 9- 8- 6- 5- 2- 1 10- 8- 7- 3 2- 1- 8 7- 6- 4- 3- 2- 1. 0 0 10 15 5 10 5 10 5 10 15 15 15 20 25 30 35 40 Number of characters. 20 25 Number of characters 71 30 35 40 1 20 25 30 35 Number of characters 20 25 30 35 Number of characters 45 40 40 50 55 45 50 55 45 50 45 50
