Chapter 9: Q 1.3. (page 570)

For the job satisfaction study described in Section 9.1, the hypotheses are

H0鈭�渭=0Ha:渭鈮�0

where 渭is the mean difference in job satisfaction scores (self-paced -machine-paced) in the population of assembly-line workers at the company. Data from a random sample of 18workers gave x=17and sx=60

Now use your calculator to find the P-value as described in the Technology Corner. Is your result consistent with the value you obtained in Question 2?

Short Answer

Expert verified

The P-value is 0.221

Step by step solution

01

Given information

Degree of freedom (df)=17

Test statistic (t)=1.27

02

Concept

test statistic = statisticparameterstandarddeviationofstatistic

03

Calculation

The P-value technology can be computed as:

The above value is for one-tailed.

The P-value for two-tailed can be calculated as: P鈭�value=2脳0.1105=0.221

Here, also the P-value is 0.221

Thus, it could be said that the obtained P-value is matching to the value that has been computed in the previous problem.

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures

students鈥� attitudes toward school and study habits. Scores range from 0 to 200. The mean score for U.S. college students is about 115. A teacher suspects that older students have better attitudes toward school. She gives the SSHA to an SRS of 45

of the over 1000 students at her college who are at least 30 years of age.
