Question

A health psychologist wanted to test if discussing the health disparities of a patient with their family would help the family deal with loss better after the patient passes from the disease. They took a survey from n=20 people and had them rate their feelings on a survey that had a rating of 1-100 where 1=total despair to 100= felt a sense of well being with the experience. They wanted to test a sample they collected from their local hospital and compare it with the national averages, which was µ=40 points and includes the population standard deviation of =70 points. The following are the raw scores from their survey: 35, 47, 78, 64, 89, 38, 55, 48, 65, 52, 72, 25, 34, 55, 52, 66, 80, 75, 54, 50. They used an alpha level of α=.05 for their criteria.
State the hypotheses of the study.
b. Find the critical tvalue for this study
c. Compute the one sample ttest
d. State the results in APA format (numbers and words) and don’t forget to include all parts in the sentence and the direction of the results.

Expert Solution

Step 1

given information :n=20

µ=40 , $σ = 70$ , $α = 0.05$

x_bar=56.7

hypothesis define:

$\begin{array}{l} H_{0} . u = 40 \\ H_{1} : μ n o t e q u a l t o 40 . \end{array}$

test statistics: $\frac{x_b a r - μ}{\frac{s}{\sqrt{n}}}$

$t = \frac{56.7 - 40}{\frac{70}{\sqrt{20}}}$

=1.06692
