Step-by-step explanation:

Answer 2

First choice:

• Most of the data in each plot are greater than 48.

Step-by-step explanation:

1. Boy's Heights.

Using the information you can create a frequency table:

Heigth Frequency

40 0

41 1

44 3

46 3

48 2

50 3

52 4

54 4

56 0

58 0

60 0

======

20 boys

2. Girl's Heights.

Similarly, create your frequency table:

Height Frequency

40 0

41 0

42 0

44 2

46 3

48 1

50 3

52 4

54 3

56 4

58 0

60 0

======

20 girls

Which is a true statement for most of the data in each plot?

Most of the data in each plot are greater than 48.

• Count the dots or add the frequencies from the tables.

• For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).

• For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.

Hence, it is correct that most fo the data in each plot are greater than 48.
