Suppose two samples of the same size, Sample 1 and Sample 2, are related as follows: Sample 2 is obtained by adding a constant to every element of Sample 1. If all else remains the same and we calculate the point estimates of the mean for samples 1 and 2, which of the following statements is true? Select one: 0 the point estimates and the standard deviations are the same for both samples 0 the point estimates are the same but the standard deviations are different for both samples 0 the point estimates are different but the standard deviation is the same for both samples 0 the point estimates and the standard deviations are different for both samples Union leaders at a company want to seek workers' opinions on a proposed labour-management contract. The table below shows the survey responses. We wish to conduct a Chi-Square test of independence. If the p-value is 0.216, at the 5% level of signicance, the conclusion is: Select one: 0 Gender and opinion are dependent 0 Gender and opinion are not dependent 0 Gender and opinion are not independent 0 Gender and opinion are related The probability of a positive test for a person who has a bacterial infection, is 0.80. The probability of a positive test result, for a person who is not infected, is 0.04. Which of the following probability statements represents a negative test result for a person who is actually infected. Select one: 0 P(Negative test result I Infection is present) 0 P(Infection is presentl Positive test result) 0 P(Infection is presentl Negative test result) 0 P(Negative test result I Infection is not present)
