1) A study found that nearly nine in every 10 students exceeded the recommended two-hour daily limit on non-school screen time during distance learning. The statistician will test if this finding also applies to grade 11 students at ABC school using a sample of at least 30 students. 2) The statistician will also test if ABC grade 11 students have at least 60 minutes of physical exercise daily as recommended. 3) It is recommended students have an internet speed of at least 1.5 Mbps for online classes. The statistician will test if ABC grade 11 students meet this minimum internet speed requirement using data from the sample.

Engaging Scenario:

Due to the covid-19 pandemic, classes have been online since the school year 2020-2021. Students
could not help but attend classes using different gadgets such as desktop computers, laptops, tablets, or
mobile phones. This exposes them to too much screen time – the time spent by a person in front of a
screen be it a television screen, laptop, or any gadget. Health authorities such as the Canadian 24 hour
Movement Guidelines for Children and Youth recommend just two hours of screen time per day (school
work doesn’t count toward this total), plus at least 60 minutes of exercise for kids and teens ages 5 to
17. A study found out that nearly nine in every 10 exceeded the recommended two-hour daily limit on
non-school screen time.*

You are a statistician from the Department of Education Quezon City Division Office and you are tasked
to conduct hypotheses testing at 0.05 level of significance to answer the following questions. The results
of this study will be used to recommend additional guidelines for the conduct of distance learning in the
coming school year.

1) Is the result of the study mentioned above that nearly nine in every 10 students exceeded the
recommended two- hour daily limit on non-school screen time also applicable to ABC grade 11
students?

2) Do ABC grade 11 students have at least 60 minutes of physical exercise?

3) It is recommended that students must have at least an internet connection speed of 1.5 Mbps in
order to attend online classes. Is there enough evidence that ABC grade 11 students have internet speed
at home higher than the minimum requirement for online classes?

PROCEDURE AND GUIDE QUESTIONS:

1) All Grade 11 students will be asked to accomplish a google form where they will indicate the number
of hours of their non-school screen time, the approximate number of minutes of daily exercise that they
do, and the average download speed of the internet connection they use for their online classes. You
will employ random sampling to get a sample of at least 30 students and their corresponding responses
to this google form. You will be given access to the Google sheet containing the responses to the form.

2) Organize and describe the data of your sample by constructing a frequency distribution for each
variable (number of hours of their non-school screen time, the approximate number of minutes of daily
exercise that they do, and the average download speed of the internet connection they use for their
online classes).

3) Show the complete step by step procedure in hypothesis testing to answer the given questions.
You can use PowerPoint, Word, Google Slides or Google Docs, whichever is most convenient to you in
presenting your work.
