Final answer:
To find the probability, we need specific distribution or data for adult females.
Step-by-step explanation:
To find the probability that a randomly selected adult female has a pulse rate less than 83 beats per minute, we need to use the information given. The problem states that an infant's pulse rate is measured to be 130 ± 5 beats per minute. This means that the pulse rate can be anywhere from 125 to 135 beats per minute.
Since this is an infant's pulse rate and we are looking for the pulse rate of an adult female, we cannot directly use this information to find the probability. We need a specific distribution or data for adult females. Without that information, we cannot calculate the probability.
