Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

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.
