The body temp of normal healthy persons are normally distributed with a mean of 98.2 degrees F and a standard deviation od .62 degree F. If we define a fever to be a body temp above 100 degrees F, what percentage of normal and healthy person would be considered to have a fever?

  • statistics -

    μ=98.2
    σ=0.62
    Z(100)=(100-98.2)/0.62=2.903
    Look up (normal) probabilities for Z=2.903 from tables (for people with temperatures below 100).
    Subtract from 1 to get probabilities of healthy person considered having a fever.
