Question

Directions: Use the Crosstabs option in the Descriptives menu to answer the questions based on the following scenario. (Be sure to select Chi-square from the Statistics submenu and Observed, Expected, Row, and Column in the Cells submenu. Assume a level of significance of .05)

The school district recently adopted the use of e-textbooks, and the superintendent is interested in determining the level of satisfaction with e-textbooks among students and if there is a relationship between the level of satisfaction and student classification. The superintendent selected a sample of students from one high school and asked them how satisfied they were with the use of e-textbooks. The data that were collected are presented in the following table.

Student Classification (N = 115)

Satisfied	Freshmen	Sophomore	Junior	Senior
Yes	11	13	21	20
No	23	15	14	9

Of the students that were satisfied, what percent were Freshmen, Sophomore, Junior, and Senior? (Round your final answer to 1 decimal place).

State an appropriate null hypothesis for this analysis.

What is the value of the chi-square statistic?

What are the reported degrees of freedom?

What is the reported level of significance?

Based on the results of the chi-square test of independence, is there an association between e-textbook satisfaction and academic classification?

Present the results as they might appear in an article. This must include a table and narrative statement that reports and interprets the results of the analysis.

Answer 1

There is an association between the two variable

There is no association between the two variable

of the students that were satisfied:

Freshmen were =16.9%

Sophomore were =20%

Junior were =32.3%

Senior were =30.8%

Test statistic:

degree of freedom = (number of rows -1)(number of columns-)=3

P value is 0.020

Level of significance =0.05

Since the P value is less than the significance level, we can reject the null hypothesis. Hence we have evidence that there is no association between e-textbook satisfaction and academic classification?
