For smaller sample sizes, the sample mean could be quite different from the population mean, and this is reflected in t ...

... The integration problem can be reformulated as follows. The volume under the integrand's surface equals its mean value times the area of the integration region. (This is true! Think about it for a while, if it is not obvious. You may want to think in terms of some simple one-dimensional examples fir ...

... c. What will be your decision at alpha of 0.05? Fail to reject H0 d. What is the p-value for this study? 2*P(z>1.5) = 2*(1-0.93319) = 2*0.06681=0.13362 e. Using the p-value, what is your decision? Fail to reject H0 16. Do the above problem, with the only difference that the sample size is 16 instead ...

The intuition behind this is that central limit theorem can be used to justify using the test for normal population. Even if σ2 is ...
