You can put this solution on YOUR website! In a certain city 37% of all shops advertise in the local newspaper. A random sample of 12 shops is taken.Define the random variable for this situation and list its values.
What in your view is the probability distribution of this variable?
Ans: Binomial
-------------------------
State the conditions that influence your choice of distribution.
same propability for each shop; advertise or do not;
-------------------------------
) Calculate the probability that more than 9 shops advertise in the local
newspaper
P(10<= x <=12) = 1 - P(0<= x <=9) = 1 - binomcdf(12,0.37,9) = 0.0014
