A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogramfor the systolic blood pressure readings for those people aged between 25 and 40. Use the histogram to answer thequestion. The blood pressure readings were given to the nearest whole number.
-Given that 300 people were aged between 25 and 40, approximately how many had a systolic blood pressure reading less than 130?

Based on the given age range (25-40), it's reasonable to infer that the majority of individuals would have a normal or near-normal systolic blood pressure, which is often considered to be less than 130 mmHg for healthy adults. Without specific statistical data provided, the most logical assumption is that a significant majority, hence option C (222), represents those with a systolic blood pressure reading less than 130. This choice aligns with general health statistics indicating that a large portion of adults in this age group would not yet have high blood pressure.
