Of these 5 mtion Of the 14 jurors selected, 2 are minortes residents, t is known hat 9% are of a minorty race (a) What proportion ot the jury descibed is from a minorty race? b) if 14 ju ors are randomly selected to apopulation where 39% are m (c) what might te wyer or a defendant from this manoty race argue? ones what is the probably that 2 or fr erpr swf be mores? (2) The proportion of the jury descreed that s tom a minorty tacee() Round to two decimal places as needed) Enter your answer in the answer bex and then click Check Answer 8Explanation / Answer
a.
Proportion of jury from minority race = 2/14 = 0.14
b.
P(2 or fewer minority from 14) = P(0 is minority) + P(1 is minority)+ P(2 are minority)
C(14,0)*(0.39^0)*(0.61^14) + C(14,1)*(0.39^1)*(0.61^13) + C(14,2)*(0.39^2)*(0.61^12) +
Cumulative probability:P(X < x) :0.046567
c.
As the probablity of selecting less than 2 minority is less than 5% this looks unusual event and may be biased
