Problem 17

A medical scientist believes that the average basal temperature of (outwardly) healthy individuals has increased over time and is now greater than 98.6 degrees Fahrenheit (37 degrees Celsius). To prove this, she has randomly selected 100 healthy individuals. If their mean temperature is 98.74 with a sample standard deviation of 1.1 degrees, does this prove her claim at the 5 percent level? What about at the 1 percent level?

Step-by-Step Solution:
Step 1 of 3

Chapter 19 Simulation  Used to find probability in complex situations  Always start with a good model  Repetition of which a event will eventually be closer to the probability. Steps in assimilation: 1. Give a model 2. Assign digits to rep the outcomes 3. Simulate repetitions ( Random digits table) Tree diagram- representation of presenting complicated probabilities Different branches: represent different stages IF asked for an intersection (and) you multiply: Ex: what is the probability of surviving AND the transplant is a success. IF asked for a union (or) you add: What is the probability of living OR dying Chapter
