Extracted text: As the school year 2020-2021 geared off, the number of hours students spend in online activity has reached an average of 6 hours a day. To test this claim, conduct a survey among 20 classmates and ask for the number of hours they spend for online activities (If the survey among classmates is not possible, you may ask other students you know through text message or chat for physical distancing during this time of pandemic). Solve the sample mean given the sample standard deviation of 2 hours. Using a 95% level of significance, decide whether the claim is true or not.
