Answer:

Step-by-step explanation:

1). Number of students in the survey = Total of frequencies

                                                            = 3 + 5 + 4 + 6 + 3 + 1

                                                            = 22

2). Range of number of pets = 6 - 1 = 5

3). Number of pets most student have = Highest frequency of the number of pets

                                                                = 4 pets

4). For the median number of pets,

   Arrange the frequencies in the increasing order,

   1, 3, 3, 4, 5, 6

   Since number of terms are even, median of the data will be the average of middle two terms.

   Middle terms of the frequencies are 3 and 4.

   Therefore, average of these numbers = [tex]\frac{3+4}{2}=3.5[/tex]

   Therefore, median number of pets = 3.5
