Long or short? Put the names of all the students in your statistics class in a hat. Mix up the names, and draw 4 without looking. Let X = the number whose last names have more than six letters.

Short Answer

Expert verified

The given statement is correct, is based on the binomial distribution.

Step by step solution

01

Given Information

The Trials is conductedn=4

X = the number whose last names have more than six letters.

02

According to the given question

The random variable X satisfies the following requirements.

1. There is no indication of the likelihood of success. As a result, it isn't corrected.

2. The number of names is set.

3. The names on the slips are not unrelated to one another.

4. There are two possibilities.

All of the binomial criteria are not met in this case.

As a result, X can be considered to follow the binomial distribution.

1 in 6 wins As a special promotion for its 20-ounce bottles of soda, a soft drink company printed a message on the inside of each bottle cap. Some of the caps said, "Please try again!" while others said, "You're a winner!" The company advertised the promotion with the slogan " 1 in 6 wins a prize." Grayson's statistics class wonders if the company's claim holds true at a nearby convenience store. To find out, all 30 students in the class go to the store and each huys one 20-ounce bottle of the soda.

a. Find the probability that two or fewer students would win a prize if the company's claim is true.

b. Two of the students in Grayson's class got caps that say, "You're a winner!" Does this result give convincing evidence that the company's 1-in-6 claim is false?
