4 The following frequency histogram represents the IQ scores of a random sample of seventh-grade students. IQs are measured to the nearest whole number. The frequency of each class is labeled above each rectangle. Use the histogram to answers parts (a) through (9). IQs of 7th Grade Students 80- 60- 52 40 Frequency 40- 33 20- 13 7 4 2 TO 1 4 60 70 80 90 100 110 120 130 140 150 160 IQ scores (a) How many students were sampled? students (b) Determine the class width.

O A. 60-69 O B. 65 O C. 150-159 O D. 60-70 (f) What percent of students had an IQ of at least 120? % (Type an integer or a decimal. Do not round.) (9) Did any students have an IQ of 166? O A. No, because there is a bar in the 150-159 class. O B. No, because there are no bars, or frequencies, greater than an IQ of 160. O C. Yes, because there is a frequency of a score of 165. O D. Yes, because there is a bar in the 150-159 class.

For example, using a bar graph versus a time series plot can make a large difference. Health Care Expenditures O B. The scales used in the graph can significantly affect the message. Also, the variable used to convey the message on the graph can make a large difference as well. O C. Values can be left out of the graph so that the graph supports the position.
