Transcribed Image Text:From the given information in each case below, use technology to find the P-value for a chi-square test and give the conclusion for a significance level of a = 0.01. (Use technology to calculate the P-value. Round your answers to four decimal places.)
USE SALT
(a) x² = 7.60, df = 2
P-value =
State the conclusion.
O Reject Ho.
O Fail to reject Ho.
(b) x² = 12.90, df = 6
P-value =
State the conclusion.
O Reject Ho.
O Fail to reject Ho.

Transcribed Image Text:In a sample of 170 students at an Australian university that introduced the use of plagiarism-detection software in a number of courses, 51 students indicated a belief that such software unfairly targets students. Does this suggest that a majority of students at the
university do not share this belief? Test appropriate hypotheses at level 0.05. (Let p be the proportion of students at this university who do not share this belief.)
State the appropriate hypotheses.
Ho: p > 0.50
H₂: P = 0.50
Ho: p = 0.50
H:p> 0.50
Ho: P = 0.50
Ha: P < 0.50
O Ho: P = 0.50
H₂: P = 0.50
USE SALT
Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.)
