Answer #1

Answer:-

We use standard normal area curve to answer these questions.

1) P(Z < -0.63 )= 0.26435 = 0.2643 (rounded to four decimal place )

2) P(Z > -2.97) = 1 - P(Z < -2.97)

= 1 - 0.001489 = 0.998511 = 0.9985 (rounded to 4 decimal places)

Homework 7- Normal Distribution Score: 0/17 0/17 answered Question 16 The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 70 with a standard deviation of 7.4. Assume that the distribution is approximately normal. Find the probability that an elite athlete has a maximum oxygen uptake of at least 89.2 ml/kg. Find...
