1. You wish to test the null hypothesis = 12.8 against the alternative hypothesis > 12.8, and you can assume the underlying population is normally distributed. What calculated (observed) value will you use if you have a sample of n = 50 and s = 13.6?State your answer to 3 places of decimal.
2. Find and state the p-value in question 1. State your answer to 3 places of decimal.
3. The sodium concentration in whole blood (mEq/L) was determined for two samples of eels. For n = 20 marine eel, s = 40.5; while for n = 20 freshwater eels, s = 32.1. What critical value would be used to test, at the 5% level of significance , to see if there is evidence that there is more variability in the marine eel data? State your answer to 2places of decimal.
4. The sodium concentration in whole blood (mEq/L) was determined for two samples of eels. For n = 20 marine eel, s = 40.5; while for n = 20 freshwater eels, s = 32.1.What is the calculated value of the test statistic to investigate whether there is more variability in the marine eel data than the freshwater eel data?.State your answer to 2places of decimal.
5. The test used with the null hypothesis ₁ = ₂ is not the same as the test used with the null hypothesis = ₀ where ₀ is a constant.
