To evaluate a CDF use Desmos only where directly indicated, otherwise use the attached z-score and areas tables and show all steps.

Clearly explain and justify the solution using proper terminology and notation.

3. The retail price of a medium-sized box of
cornflakes ranges from $2.80 to $3.14. Assume
these prices are uniformly distributed.

a) What are the average price and the standard
deviation of prices in this distribution?

b) If a price is randomly selected from this list,
what is the probability that it will be between $3.00
and $3.10?

c) If you know that the probability of price being
less than c in this distribution is 15%, evaluate c.
