Assume that females have pulse rates that are normally distributed with a mean of u = 76.0 beats per minute and a standard deviation of o = 12.5 beats per minute. Complete parts (a) through (c) below. a. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 80 beats per minute. The probability is 0.6255. (Round four decimal places as needed.) b. If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 80 beats per minute. The probability isO (Round to four decimal places as needed.)

![**Pulse Rate Probability Analysis**
Assume that females have pulse rates that are normally distributed with a mean (μ) of 76.0 beats per minute and a standard deviation (σ) of 12.5 beats per minute. Complete the following probability analysis:
a. **Single Female Pulse Rate Probability**
- **Task**: Find the probability that a randomly selected adult female has a pulse rate less than 80 beats per minute.
- **Result**: The probability is 0.6255. (Round to four decimal places as needed.)
b. **Group Average Pulse Rate Probability**
- **Task**: If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 80 beats per minute.
- **Result**: The probability is [ ]. (Round to four decimal places as needed.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F673bdf8c-8860-43be-b763-ccedc64692ee%2F7d4cba00-6146-4791-a51a-7c4b2e380665%2Fgt132f_processed.png&w=3840&q=75)
