Final answer:
To find the probability that the pulse rate of a randomly selected adult female is less than 80 beats per minute, we need to know the mean and standard deviation of the pulse rate for the population of adult females. Without this information, we cannot calculate the probability accurately. However, if we assume a normal distribution with a mean of μ and a standard deviation of σ, we can use a normal distribution table or a calculator to estimate the probability.
Step-by-step explanation:
To find the probability that the pulse rate of a randomly selected adult female is less than 80 beats per minute, we need to know the mean and standard deviation of the pulse rate for the population of adult females. Without this information, we cannot calculate the probability accurately. However, if we assume a normal distribution with a mean of μ and a standard deviation of σ, we can use a normal distribution table or a calculator to estimate the probability.
Let's assume a normal distribution with a mean of μ = 75 and a standard deviation of σ = 10. To find the probability that the pulse rate is less than 80 beats per minute, we can calculate the z-score for 80 using the formula z = (x - μ) / σ, where x is the value we want to find the probability for.
So, z = (80 - 75) / 10 = 0.5. Using the z-score table, we can find that the probability for a z-score of 0.5 is approximately 0.6915. Therefore, the probability that a randomly selected adult female has a pulse rate less than 80 beats per minute is approximately 0.6915.
