Question

Do you trust the Internet? You want to ask a sample of high school students the question “How much do you trust information about health that you find on the Internet—a great deal, somewhat, not much, or not at all?” You try out this and other questions on a pilot group of $5$students chosen from your class.

a. Explain how you would use a line of Table D to choose an SRS of $5$students from the following list.

b. Use line $107$to select the sample. Show how you use each of the digits.

Short answer

a. From $1$to $40$, assign a number to each of the $40$students.

b. Using line $107$, skip the numbers not in bold:

$8273957890208074751181676553009438314893609407$.

Step-by-step solution

Part (a) Step 1 : Given Information

The sample of $40$students is given

Part (a) Step 2 : Simplification

From $1$to $40$, assign a number to each of the $40$students. On the random number table, choose a starting point. Make a list of two-digit numbers, skipping those that aren't between $01$and $40$and any that are repeated, until you have $5$distinct numbers between $01$and $40$. Use the $5$pupils who match these numbers.

Part (b) Step 1 : Given Information

The sample of 40 students is given

Part (b) Step 2 : Simplification

Using line $107$, skip the numbers not in bold: $8273957890208074751181676553009438314893609407$. Select Johnson ($20$), Drasin ($11$), Washburn ($38$), Rider ($31$), and Calloway ($07$).
