Heart Rate (beats/min)3 A graph of average resting heart rates is shown below. The average restingheart rate for adults is 72 beats per minute, but doctors consider restingrates from 60-100 beats per minute within normal range.Use tbAverage Resting Heart Rate by Age(0,112)(20,72)(50,72)0940200 10 20 30 40 50 60Age (years)Which statement about average resting heart rates is not supported by the graph"(1) A 10-year-old has the same average resting heart rate as a 20-year-old.(2) A 20-year-old has the same average resting heart rate as a 30-year-old.(3) A 40-year-old may have the same average resting heart rate for ten years.(4) The average resting heart rate for teenagers steadily decreases.

Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if the glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink. Shelia's measured glucose level one hour after the sugary drink varies according to the Normal distribution with µ = 124 mg/dl and σ = 13 mg/dl. If a single glucose measurement is made, what is the probability that Shelia is diagnosed as having gestational diabetes?
Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.

A team of UMD students have invented an inhalable drug that they think will help people breathe better during hard exercise. They test the drug on 3 volunteers (A, B, and C) by measuring their levels of arterial oxygen before receiving the drug (their base level) and then after 5 and 10 minutes have elapsed, respectively. The results are listed in the table. Oxygen level [mmHg] A B C base level 847076 after 5 minutes 85 74 81 after 10 minutes 90 75 98 We want to see how the drug work (better or worse) when compared to the base level.
