When individuals in a sample of 150 were asked whether or not they supported capital punishment, the following information was o

Roman55 [17]

Answer:

Option C.

Step-by-step explanation:

Given information:

Sample size = 150

Number of Opinions = 3 (Yes, No, No Opinion)

Yes = 40

No = 60

No opinion = 50

We need to find the expected frequency for each group.

Expected frequency for each group is the quotient of sample size and number of opinions.

$\text{Expected frequency for each group}=\dfrac{\text{Sample size}}{\text{Number of Opinions}}$

$\text{Expected frequency for each group}=\dfrac{150}{3}$

$\text{Expected frequency for each group}=50$

Therefore, the correct option is C.
