Question 1
A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogram for the systolic blood pressure readings for those people aged between 25 and 40. Use the histogram to answer the question. The blood pressure readings were given to the nearest whole number.
Given that 200 people were aged between 25 and 40, approximately how many had a systolic blood pressure reading less than 130?
◦ 48
◦ 15
◦ 148
◦ 74
Question 2
A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogram for the systolic blood pressure readings for those people aged between 25 and 40. Use the histogram to answer the question. The blood pressure readings were given to the nearest whole number.
Identify the midpoint of the third class.
◦ 124
◦ 130
◦ 125
◦ 120
The nurse uses a noninvasive bladder ultrasound to measure the client’s bladder volume.
Automated blood pressure monitor
Major three factors of blood pressure.
