Connor believed that he did not do well in his ABC physics test. All ABC physics test scores are normally distributed with a mea
n of 20 and standard deviation of 8. A student gets an F grade if he or she scores less than 5. If Connor is at the 20th percentile, does he pass the test?
The answer is 13 trust me. the answer should be 29 for no reason. but answer 13 and you'll get it right.
I don't know how to take a screen shot and post. but the easy way is to count . so 50 years old = 15. 60 years old = 8. 70 years old = 4. 80 years old = 2. add them.
