Shown here are four frequency distributions. Each is incorrectly constructed. State the reason why.

Tanya [424]

Answer/Step-by-step explanation:

a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.

b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.

c. In the 3rd row, the lower limit of the class should be 133, NOT 138.

d. Different class width were used.

Row 1 class width = 13 - 9 = 4

Row 2 class width = 19 - 14 = 5

Row 3 class width = 25 - 20 = 5

Row 4 class width = 28 - 26 = 2

Row 5 class width = 32 - 29 = 3

RUDIKE [14]

Answer:

Step-by-step explanation:

In first voting 300 person favors the candidate out of 500

i.e. $\frac{300}{500}=0.6$

60 % Population favor the candidate

For second voting 550 person favors the candidate out of 1000 candidates

i.e. $\frac{550}{1000}=0.55$

55 % Population favors candidate

so according to voting, 1 st voting is favorable for candidate because a large population support him as compared to second voting.
