Monsters were surveyed as they left Harryhausen'sSushi Restaurant. Since70 out of 75 monsters said they would surely eat there again, a local newspaper declared Harryhausen's Sushi Restaurant the best restaurant in the Monster World. Why might that declaration be misleading? A The survey did not include more monsters from the restaurant. B They did not give a gift certificate to everyone who completed the survey. C They did not survey customers at restaurants across Monster World. D The survey did not ask customers what they ordered

Step-by-step explanation:

mode = n

median= n+1

mean = n+2

Range = n+3

let sets:

a,b,c,d,e

mode = n, at least two of them are the same and equal to n

n,n,c,d,e

median belong to the set, in ascending order:

n,n,n+1,d,e

which means d,e ≥ n+1, d≠e

mean is n+2

5(n+2)=n+n+n+1+d+e

2n+9=d+e

Assume e is the maximum:

Range is n+3:

e-n=n+3

e=2n+3

d=6≥n+1

n≤5,

Set is n,n,n+1,6,n+3

n+1≤6≤n+3

3≤n≤5

3,3,4,6,6 bimodal

5,5,6,6,8 bimodal
