ASSIGNMENT 3 2024
QUESTION 1
1.1. In this module, the standard level of significance is consistently stated as 0.005.
(a) However, this is false. Typically, we operate with significance levels of 5% or 1%,
represented as 0.05 or 0.01, respectively.
A Type I error is made by rejecting the null hypothesis when it is in fact true.
True- There are two types of errors, Type 1 and Type 2. A Type I error means rejecting a
null hypothesis when it is true. A Type II error means not rejecting a null hypothesis when
it is false.
If you get a negative value for the F-test, this means the test statistic falls inside the
rejection area. False- We never observe negative F-values.
, 1.2. There is a significant difference between the performance of students in Assessment 01
(a) and Assessment 02.
Non Directional- the two variables are not equal
(b) Participation in e-tutor sessions is positively related to student performance of IOP2601
students.
Directional- one variable is larger than the other.
(c) Directional The performance of IOP2601 students who attend tutorial classes is higher
than the performance of IOP2601 students who do not attend tutorial classes.
Directional- one variable is larger than the other
