Question

twenty percent of adults in a particular community have at least a bachelors degree. suppose x is a binomial random variable that counts the number of adults with at least a bachelors degree in a random sample of 100 adults from the community. which of the following probability statements indicates the probability that more than 30 adults have at least a bachelors degree? choose the correct answer below. a. p(x>30) b. p(x<30) c. p(x≥30) d. p(x≤30)

Explanation:

Step1: Identify the condition

We want probability of more than 30 adults.

Step2: Translate to probability notation

In probability, "more than 30" for a random - variable \(x\) is written as \(P(x > 30)\).

Answer:

A. \(P(x>30)\)
