Summer high temperatures are distributed normally with a mean of 99.6 and a standard deviation of 3.9. NOTE: Round your z − score to 2 decimal places before calculating a probability.

What is the summer high temperature that is the 84 th percentile of this distribution? 102.9 96.3 103.5 95.7 None of the above

What is the probability that a randomly selected summer day has a high temperature of 101? 0 0.6406 0.3594 0.0594 0.9406

What is the probability that a randomly selected summer day has a high temperature greater than 101? 0.9406 0.3594 0.6406 0 0.0594

What is the probability that a randomly selected group of 19 summer days have a high temperature greater than 101? 0.3594 0.9406 0.6406 0.0594 0
