Question

1. Suppose you are interested in knowing how many text messages eleventh graders send daily.

Describe the steps that you would take to estimate the mean number of text messages per day sent by all eleventh graders at a school.

Answer 1

Mean estimate is gotten by dividing total number of text messages for a month(or whichever period you choose, longer more accurate) by number of days in that month.

Explanation:

-share questionnaires to students( 11th graders) at school daily asking how many messages they send per day. Collect immediately.

-do this for a month. This is to ensure they give less inaccurate answers.

-add up to get total value of text messages in a month

-divide this by number of days in the month

The number you get is the mean estimate of text messages sent by 11th graders per day(using a period of one month)
