Question

Based on a survey, 34% of likely voters would be willing to vote by internet instead of the in-person traditional method of voting. For each of the following, assume that 16 likely voters are randomly selected.

Part A) What is the probability that exactly 13 of those selected would do internet voting?
(Round to five decimal places as needed.)
Part B) if 13 of the selected voters would do Internet voting is 13 significantly high? Why or why not?
Part C) find the probability that at least one of the selected likely voters would do Internet voting?

Answer 1

To find the probability that exactly 13 of the 16 selected likely voters would do internet voting, we can use the binomial probability formula.

Step-by-step explanation:

To find the probability that exactly 13 of the 16 selected likely voters would do internet voting, we can use the binomial probability formula. The formula is:

P(X = k) = C(n, k) * p^k * (1-p)^(n-k)

where n is the number of trials, k is the number of successful outcomes, p is the probability of success, and C(n, k) is the binomial coefficient. In this case, n = 16, k = 13, and p = 0.34. Plugging these values into the formula, we get:

P(X = 13) = C(16, 13) * 0.34^13 * (1-0.34)^(16-13)
