What is the critical value for this test? (Report answer accurate to three decimal places.) critical value = What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = The test statistic is... in the critical region O not in the critical region This test statistic leads to a decision to... reject the null accept the null O fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 66.6. OThere is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 66.6. The sample data support the claim that the population mean is not equal to 66.6. There is not sufficient sample evidence to support the claim that the population mean is not equal to 66.6.
