Question 1 of 7 Points: 10
A teacher is experimenting with a new computer-based
instruction and conducts a study to test its effectiveness. In which
situation could the teacher use a hypothesis test for matched
pairs?
The teacher gives each student in the class a pretest. Then she teaches a lesson using a
computer program. Afterwards, she gives each student a post-test. The teacher wants to see if the differe
The teacher randomly divides the class into two groups. One of the groups receives computer-
based instruction. The other group receives traditional instruction without computers. After instruction
The teacher uses a combination of traditional methods and computer-based instruction. She
asks students which they liked better. She wants to determine if the majority prefer the computer- based instruction.
Question 2 of 7 Points: 10
Research suggests that identical twins have many similarities, such as
body weights, even as adults. A sample of ten sets of identical twins were
weighed and had their weights recorded in kilograms. The researcher
wishes to test whether there is a statistically significant difference in adult
weight between first-born and second-born identical twins.
Given the design of the study and the question of interest, which of the following 4 computer outputs is relevant to use?
, answer is c
