In this part of the question, you should calculate the required probabilities using tables, show your
working. (Can check your answers, if you wish.)
A model for normal human body temperature, X, when measured orally
in °F, is that it is normally distributed, X ~ N (98.2, 0.5184).
(i) According to the model, what proportion of people have a normal
body temperature of 99 °F or more?
(ii) Find the normal body temperature such that, according to the
model, only 10% of people have a lower normal body temperature.
(iii) Let W denote normal human body temperature, when measured
orally in °C. Given that W = ¿(X – 32) and X ~ N(98.2, 0.5184),
what is the distribution of W?
(iv) According to the model that you just derived for W, what
proportion of people have a normal body temperature of between
36 °C and 36.8 °C?
