Question

measure the length of his pencil with a ruler times. The student assumes that measurements of this type are normally distributed. Student culates a mean length of 3.47 inches, with probability of being I standard deviation off in a mean of 3.47 also, but her probability of being I standard deviation off in either direction is Student A 100 finishes his exam early, so he decides to either direction equal to 0.20. Student B takes the pencil and repeats the experiment. She obtains Which student had lower standard deviation? Which student do you believe did a better job 0.23. measuring? Explain both answers.

Explanation / Answer

Student A have the higher standard deviation because the probability of being 1 standard deviation off in either direction is 0.20 which is less than 0.23 for Student B
