The parameters of the normal distribution of the thermometer readings are its mean and the standard deviation
The probability that a thermometer reading is between 99.86o F and 100.07o F is 0.5403
The given parameters are:
Next, we draw the normal distribution using a graphing calculator.
See attachment for the sketch of the normal distribution of the thermometer
This means that:
x = 99.86 and x = 100.07
The probability is calculated as:
P(99.86 < x < 100.07) = P(x > 99.86) - P(x < 100.07)
Using the attached graph, we have:
P(99.86 < x < 100.07) = 0.5403
