Answer to Question #175086 in Statistics and Probability for Reive Lawrenz Labiaga

Question

Students are asked to count the number of chocolate chips in 22 cookies for a class activity. They found that the cookies on average had 14.77 chocolate chips with a standard deviation of 4.37 chocolate chips. After collecting the data, a student reports the standard error of the mean to be 0.93 chocolate chips. What is the best way to interpret the student’s result?

a.0.93 chocolate chips is a measure of the variability we’d expect in calculations of the mean number of chocolate chips if we took repeated random samples of 22 cookies.

b.0.93 chocolate chips is a measure of the variability in the mean number of chocolate chips across all chocolate chip cookies.

c.0.93 is the standard deviation of the number of chocolate chips in a chocolate chip cookie.

d.The student either made a calculation error or his result is meaningless, because it does not make sense to talk about 0.93 chocolate chips.

Answer 1

a.0.93 chocolate chips is a measure of the variability we’d expect in calculations of the mean number of chocolate chips if we took repeated random samples of 22 cookies.
