A chi-squared test of a contingency table with 10 degrees of freedom results in a test statistic of 17.894 . Using the chi-squared table, the most accurate statement that can be made about the p-value for this test is that .05 < p-value < .10.
Indicate whether the statement is true or false

b. expected net present value.
c. expected value of perfect information.
d. expected rate of return.
Q. 3A chi-squared test of a contingency table is applied to a contingency table with 4 rows and 4 columns for two qualitative variables. The degrees of freedom for this test must be 9.
Indicate whether the statement is true or false
Q. 4Which of the following statements is correct?
a. The EMV criterion selects the act with the largest expected monetary value.
b. The EOL criterion selects the act with the smallest expected opportunity loss.
c. The expected value of perfect information (EVPI) equals the smallest expected opportunity loss.
d. All of these choices are true.
Q. 5A chi-squared test of a contingency table is applied to a contingency table with 3 rows and 4 columns for two qualitative variables. The degrees of freedom for this test must be 12.
