According to a national survey, 92% of U.S. dog owners consider their pets to be members of the family. In a random survey of 150 dog owners, what is the probability that at most 132 of them consider their pets to be members of the family?

Does anyone know how to solve this question? I don't understand how to do it.

perl · Answer

Let X = # of people who consider their pet to be a member of family
Then X = 0,1,2,3... 150
You can use a TI 83 calculator
P ( X<= 132) = binomcdf( 150, .92, 132)
