Question

Dogs 36.5% 43,346,000 1.6 69,926,000 2.6 Percent of households owning Number of households owning Average number owned per household Total number in United States Veterinary visits per household per year (mean) Veterinary expenditure per household per yea (mean) Veterinary expenditure per animal (mean) $378 $227
the question is “Create a binomial distribution frequency graph related to dog ownership”. i dont know exactly what information is needed but

the sample size is 7 and p=0.365

Answer 1

Here sample size = 7

and p = 0.365

so here if x is the number of families out of 7 families that owned dogs.

p(x) = ⁷C_x (0.365)^x (1- 0.365)^(7-x) ; x = 0,1,2,.....7

now we will calculate value of probability for given x values

x	p(x)
0	0.041631
1	0.167507
2	0.288851
3	0.276721
4	0.15906
5	0.054857
6	0.010511
7	0.000863

Here is the frequency graph

p(x) 0.35 0.3 0.25 0.2 plx) 0.15 0.1 0.05 0 0 4
