The following data was collected from 10 visitors to disneyland. a researcher stood at the entrance gate and interviewed the first 10 families that agreed to participate. each family was asked, “how many times have you been to disneyland? ” the data values were: 1, 1, 2, 2, 2, 2, 3, 3, 4, 7. the average number of visits was calculated and reported.

The average no of visits are 2.7

Step-by-step explanation:

Given values = 1,1,2,2,2,2,3,3,4,7

We have to find the average of the values

We know that

Average =Total sum of all observations/ No. of observations

No of observations = 10

Hence average of these values =

=

= 2.7

Hence the average no of visits by a family are 2.7

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

a negative exponent is translated as follows:

so, we have
