You wish to test the following claim ( H a ) at a significancelevel of ? = 0.05 . H o : ? = 65.3 H a : ? ? 65.3 You believe thepopulation is normally distributed, but you do not know thestandard deviation. You obtain a sample of size n = 106 with mean ¯x = 62.8 and a standard deviation of s = 16.2 . What is the teststatistic for this sample? (Report answer accurate to two decimalplaces.) test statistic = What is the p-value for this sample?(Report answer accurate to four decimal places.) p-value = Thep-value is... less than (or equal to) ? greater than ? This teststatistic leads to a decision to... reject the null accept the nullfail to reject the null As such, the final conclusion is that...There is sufficient evidence to warrant rejection of the claim thatthe population mean is not equal to 65.3. There is not sufficientevidence to warrant rejection of the claim that the population meanis not equal to 65.3. The sample data support the claim that thepopulation mean is not equal to 65.3. There is not sufficientsample evidence to support the claim that the population mean isnot equal to 65.3.
