Q3. Find the following probability of the standard normal random variable Z. (round to 4 decimal places)

  P(Z ≥ –2.31)

Q4. A pediatrician obtains the heights of her three-year-old female patients. The heights are approximately normally distributed, with mean 38.72 inches and SD 3.17 inches. Determine the percentage of three-year-old females who have a height less than or equal to 35 inches.  (round to 2 decimal places)

Q5. Find the z-score such that the area under the standard normal curve to the right is 0.10. (round to two decimal places)

Please answer, if possible, in TI-84 calculator via steps. Thanks!
