The time it takes a student to finish a final exam test is known to be normally distributed with a mean equal to 84 minutes with a standard deviation equal to 10 minutes. Given this information, the probability that it will take a randomly selected student between 75 and 90 minutes is approximately .0902.
  Indicate whether the statement is true or false

Question 2

If the probability of committing a Type I error is set at 0.10, then the probability of committing a Type II error will be 0.90, since sum of probabilities must be 1.0.
  Indicate whether the statement is true or false
