Question 6

In the research question given in question 5, two variable types can be identified. These include the dependent and the independent variables. According to Hughes & Hayhoe (2007), the independent variable includes the intervention to be tested while the dependent variable essentially comprises of the result to be measured. In the research question outlined in question 5, the independent variable is caring for a pet. On the other hand, we have the dependent variable being the lifespan of a person over 65 to 75. According to McBurney and White (2009), the effects of the independent variable are reflected or mirrored on the dependent variable. In our case, caring for a pet which is the dependent variable can be said to be a measure of the behavior of the subject.

Question 7

The approach that takes into consideration the idea from all its perspectives by exploring literature extensively is known as literature review. Literature review is considered a preliminary task that helps individuals to familiarize themselves with the existing body of knowledge regarding an issue at hand (Kumar 2011).

Question 8

Basically, the null hypothesis provides a framework under which the study inferences can be reported. When it comes to errors, two kinds of the same can occur (Kumar 2011). The first error known as Type I error denotes a situation where there is rejection of a null hypothesis despite being true while the second error known as Type...

According to Hughes & Hayhoe (2007), a null hypothesis can be rejected or accepted on the basis of its p value.
Question 9

For the research question given in question 5, the hypothesis set to be disapproved will constitute the null hypothesis. Hence the null hypothesis (H0) in this case will be:

"Caring for a cat pet does not prolong life of a person over 65 to 75 living alone in the Northwestern region of the U.S.A."

In the event that the null hypothesis is disapproved after the conduction of investigations, then it shall be necessary to construct another null hypothesis.

Question 10

When it comes to either accepting or rejecting the hull hypothesis, the p value will come in handy. In this case, should the p value happen to be higher than or equal to 0.1 (which is essentially the significant level), then I will not reject the null hypothesis. On the other hand, if the p value happens to be below 0.1, this will form the basis for my rejection of the null hypothesis.
