Question4) Let say a researcher who studied on daily caloric intake for certain adult population. A research take a sample of 36 had the mean of 1900 with the sample standard deviation of 100.

a) What statistical test researcher should use?

1. One proportion test

2. One sample T-test when population variance is unknown

3. One sample T-test when population variance is known

4. None of above

c) Can a researcher conclude that the population mean of caloric intake is greater than 1801? Let alpha be at .01

1.Yes, because our test statistics is greater than T value from T table

2.No, because our test statistics is less than T value from T table
