A researcher wants to know the probability of being named on the honor roll from a population where 8% of students are on the honor roll. If the researcher selects a sample of 400 students, then what is the mean number of students expected to be on the honor roll? Hint: This is a binomial distribution, where p = 0.08 and q = 0.92.

The mean number of students expected to be on the honor roll is 32.

Explanation:

Since we have given that

Number of students = 400

Probability of students on honor roll = 8% = 0.08

p = 0.08

q = 0.92

Since it is a binomial distribution,

Mean for this sample would be

Hence, the mean number of students expected to be on the honor roll is 32.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
