8.| Distribution: Rhode Island Red Chicks The incubation time for Rhode Island
Red chicks is normally distributed with a mean of 21 days and standard
deviation of approximately I day (based on information from World Book
Encyclopedia). Look at Figure 6-3 and answer the following questions. If
1000 eggs are being incubated, how many chicks do we expect will hatch
(a) in 19 to 23 days?
(b) in 20 to 22 days?
(c) in 21 days or fewer?
(d) in 18 to 24 days? (Assume all eggs eventually hatch.) d)
a)
b)
%% =
% =
eggs
% =
eggs
c)
eggs
eggs
Note: In this problem, let us agree to think of a single day or a succession of
days as a continuous interval of time.
