Question

1. You are to model the daytime temperature of the Mojave desert during the summer time.
Temperatures in the desert are modeled to follow a normal distribution with μ = 102 Fahrenheit
and variance σ2 = 25 Fahrenheit.

 

d. Say X is the random variable that denotes the temperature during the desert day. What
distribution does 0.55 X-17.6 follow? State the type of distribution, and all parameters.
e. Now say you relax the normality assumption from the model, and you observe 25 days temper-
atures (X₁, X2, X25) from some unknown distribution. What is the approximate distribution
EX? State the approximate type of
n
of the sample mean of these daily temperatures, X
i=1
distribution and all parameters.
...
=
-
n
f. Continuing with part e, you now transform each temperature from Fahrenheit to Celsius. The
conversion is
Celsius 0.55*Fahrenheit-17.6. What approximate distribution does the sample mean in Celsius
follow? State the type and parameters.
