1) It is claimed that students use computer networks on average 5 hours a day in an educational institution consisting of 2500 students. The average duration of use of the computer alarur for 10 randomly selected students was 5.3 hours, and the standard deviation was 1.2. Create Type 1 error and Type 2 error scenarios for the situation above. In which case, Type 1 error, in which case Type 2 error would have been made, please explain on the given example
Solutions
Expert Solution
H0: Null Hypothesis: 
= 5 ( Students use computer networks on average 5 hours a day in
an educational institution ) (Claim)
HA:Alternative Hypothesis:
5 ( Students do not use computer networks on average 5 hours a day
in an educational institution )
Scenerio 1:
Type I Error: Rejection of a true null hypothesis.
Suppose in reality, students use computer networks on average 5 hours a day in an educational institution. But, we wrongly conclude that students do not use computer networks on average 5 hours a day in an educational institution. Type I Error is committed in this scenerio.
Scenerio 2:
Type II Error: Failure to reject a false null hypothesis.
Suppose in reality, students do not use computer networks on average 5 hours a day in an educational institution. But, we wrongly conclude that students use computer networks on average 5 hours a day in an educational institution. Type II Error is committed in this scenerio.

A typical college student spends an average of 2.55
hours a day using a computer. A sample of 13 students at The
University of Findlay revealed the sample mean of 2.70 hours and
sample standard deviation of 0.51 hours.
Can we conclude that the mean number of hours per day
using the computer by students at The University of Findlay is the
same as the typical student’s usage? Use the five
step hypothesis testing procedure and the 0.05 significance
level.

Students of a large
university spend an average of $5 a day on lunch. The standard
deviation of the expenditure is $3. A simple random sample of 36
students is taken.
What are the expected value, standard deviation, and shape of
the sampling distribution of the sample mean?
What is the probability that the sample mean will be at least
$4?
What is the probability that the sample mean will be at least
$5.90?
