Question

According to a recent national poll, 41% of females and 32% of males identify as democrats. Suppose a random sample of 120 females and 140 males is obtained. What is the value of the parameters for the binomial random variable X, the number of democrats in the sample of 120 females? n = (report your answer in whole numbers) p = (report your answer to two decimal places)

Answer 1

The values of the parameters for the binomial random variable X are X = Number of Democrats in the sample of 120 females, n = 120 (sample size), and p' = 0.41 (probability of a female identifying as a Democrat).

Step-by-step explanation:

To find the value of the parameters for the binomial random variable X, we need to identify the variables. In this question:

1. X represents the number of Democrats in the sample of 120 females.
2. n represents the sample size, which is 120.
3. p' represents the probability of a female identifying as a Democrat, which is 0.41.

Therefore, the values of the parameters for the binomial random variable X are:

1. X = Number of Democrats in the sample of 120 females
2. n = 120 (sample size)
3. p' = 0.41 (probability of a female identifying as a Democrat)
