sketch the normal distribution and label the indicated areas. then, compute the area under the standard normal curve.
- to the left of z=1.54 please show drawing
- to the right of z=-0.95
- between z=-2.33 & z=2.33
sketch the normal distribution and label the indicated areas. then, compute the probability using the standard normal distribution.
4. p( z<0.45)
5. P(-1.65 Assume the random variable, x, is normally distributed with u=86 and o=5. Find the indicated probability. 6. P(x<80) 7. P(85 8. P(x>75) A survey was conducted to measure the height of US men. In the survey, respondents were grouped by age. In the 20-29 age group, the heights were normally distributed, with U=69.2 inches and o=2.9 inches. A study participant is randomly selected. 9. Find the probability that his height is less than 66 inches. 10. Find the probability that his height is more than 72 inches.
