The diagram shown the histogram of the amount of time spent watching TV in a day for a group of students. Remember that the area of each rectangle is proportionate to its frequency. Find the total number of students. (Take the most common base of all rectangles a 1 unit)Select an answerA165B140C130D110

An instructor asked her students how much time (to the nearest hour) they spent studying for the midterm. The data are displayed in the following histogram:What do the numbers on the horizontal axis represent?The values of the number of hours studiedThe count of students falling in each of the intervalsWhat do the numbers on the vertical axis represent?The values of the number of hours studiedThe count of students falling in each of the intervalsWhat percentage of students study 6 or more hours for the midterm?24%48%52%72%88%

An instructor recommends to students in his introductory statistics class to spend at least 5 hours studying outside class. One of the items on the student survey for this course was "How many hours a week do you study for this class?” The instructor examined the data for men and women separately. Below is the distribution of this variable for the 30 women in the class.Part C: Which of the following boxplots represents the same data set as the histogram shown above?

In a histogram the area of each rectangle is proportional to
