Chapter 4, Problem 1.1HD

(a)

To determine

State the null hypothesis.

(a)

Expert Solution

Answer to Problem 1.1HD

The population of the rats that are given an experimental treatment took the same amount of time to learn the maze as the population of rats that are not given any experimental treatment is the null hypothesis in the study.

Explanation of Solution

Null hypothesis:

The null hypothesis denotes the statement for determining the relationship between the populations which are opposite to the researcher hypothesis. In other words, null hypothesis is the statement showing that there is no difference between the populations, this statement is included in hypothesis testing to examine whether it can be rejected or not.

The researcher has taken a sample of rats from the laboratory and is given an experimental treatment for making them learn maze faster than the other rats.

The two populations included in the study are, rats that are given an experimental treatment and rats in general, that is rats that are not given experimental treatment. The null hypothesis states that there would be no difference between the two populations.

The null hypothesis for the study is, the population of the rats that are given an experimental treatment took the same amount of time to learn the maze as the population of rats that are not given any experimental treatment.

Answer to Problem 1.1HD

The population of the rats that are given an experimental treatment learnt the maze faster than the population of rats that are not given any experimental treatment is the research hypothesis in the study.

Explanation of Solution

Research hypothesis:

The research hypothesis denotes the statement for determining the predicted relationship between the populations. In other words, research hypothesis is the statement showing that there is a difference between the populations.

The two populations included in the study are, rats that are given an experimental treatment and rats in general, that is rats that are not given experimental treatment. The research hypothesis states that there would be a difference between these two populations that is the population of rats given treatment would be faster than the population of rats in general.

The research hypothesis for the study is, the population of the rats that are given an experimental treatment learnt the maze faster than the population of rats that are not given any experimental treatment.
