Asap will give ! and 50 points
the table shows the results of four surveys that randomly sampled 50 families in a town about the number of pets their family has.
0 pets 1 pet 2 or more pets total
survey 1 12 13 25 50
survey 2 20 21 9 50
survey 3 10 13 27 50
survey 4 11 12 27 50
identify surveys that are likely biased. based on the unbiased surveys, what percent of the families in the town are expected to have 2 or more pets?
40 %
44 %
53 %
59 %

C. 53%

Step-by-step explanation:

From the table, we see that,

The number of families in Survey 1, 3 and 4 are increasing as the number of pets increases.

But, that is not happening in Survey 2. This might be due to some bias.

Thus, Survey 2 is most likely to be biased.

So, we get the unbiased survey are 1, 3 and 4.

So, the number of families in these surveys having 2 or more pets are,

Survey 1 = 25,        Survey 3 =  27,          Survey 4 = 27

So, the total number of families having 2 or more pets = 25 + 27 + 27 = 79

Also, the total number of families for the 3 surveys = 50 + 50 + 50 = 150

Thus, the percent of families having 2 or more pets = = 52.7% ≈ 53%

Hence, option C is correct.
