PLEASE SHOW ME HOW TO DO THIS

A clinic took temperature readings of 250 flu patients over a weekend and discovered the temperature distribution to be Gaussian, with a mean of 102.00°F and a standard deviation of 0.5660. Use this normal error curve area table to find the following values.

(a) What is the fraction of patients expected to have a fever greater than 103.58°F?

(b) What is the fraction of patients expected to have a temperature between 101.43°F and 102.74°F?

Rahaf,

I get 0.26% for part A and 75% for part B.  My work is in the attached document.

You have to be careful with rounding.  it's good to know how your instructor handles significant digits.  I used a TI-84 calculator to get the percentages.  If you need to know how to use the table, let me know.

Take care.
