HELP NO LINKS Jesse wants to start driving himself to and from school each day his parents want to know how much driving time would be involved so Jesse surveyed for neighbors who live on his block and drive to school data he collected is displayed in the table below

Answers

the answer is B. have a good thanksgiving

175 minutes of driving time would be involved for Jesse according to the survey.

What are the basic rules of surveying?

Some basic rules of surveying are:

Define a clear, attainable goal for your survey.Keep the more personal questions to the end. Don't let your survey get too long. Focus on using closed-ended questions. Consider including a survey incentive. Don't ask leading questions. Keep your answer choices balanced

Given, Jese wants to start driving himself to and from school each day He surveyed neighbors who live on his block and drive to school data.

For better understanding, a picture is attached below.

Add up the 8 different times then divide by 4 to get the average driving time for 1 day:

⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138

⇒ 138 ÷ 4 = 34.5 mins

Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:

⇒ 34.5 x 5 = 172.5 minutes

As 172.5 ≈ 175 minutes, the nest response is 175 minutes

Therefore, According to the study, Jesse would require 175 minutes of driving time.
