In a recent survey, it was stated that Filipino teens watch television on average 3.5 hours per
day. A teacher believes the time spent on television of students in a particular school is lower
than the national average. Using a sample of 20 from the school, the mean time spent on
studying per day is 3.1 hours with standard deviation 1.7 hours. Is this enough evidence to say
that the students in the school is lower than the national average in terms of time spent on
television per day at 5% level of significance? Assume that the time spent on television is
normally distributed and o = 2.
a. In words, define the random variable X =
b. Ho:
с. На:
d. The level of significance is
e. Determine the test statistic using the data (show solution).
f. Provide the decision rule of the test.
g. Decision:
h. Write a clear conclusion. You may use the sample format:
<There is / There is no> sufficient evidence to reject the null hypothesis that
<insert null hypothesis in words> at < _% level of significance>.
