Description
1. A test statistic for a two-sided significance test for a population mean is z = 2.0. Sketch a standard normal curve and mark this value of z on it. Find the P-value and shade the appropriate areas under the curve to illustrate your calculations. 2. The P-value for a significance test is 0.067. a. Do you reject the null hypothesis at level α = 0.05? b. Do you reject the null hypothesis at level α = 0.01? 3. The P-value for a significance test is 0.045. a. Do you reject the null hypothesis at level α = 0.05? b. Do you reject the null hypothesis at level α = 0.01? 4. A test of the null hypothesis H o: µ = µogives test statistic z = 1.72. a. What is the P-value if the alternative is Ha: µ > µ ? o b. What is the P-value if the alternative is Ha: µ < µ ? o c. What is the P-value if the alternative is Ha: µ ≠ µ ?o 5. A test of the null hypothesis H o: µ = µogives test statistic z =  1.72. a. What is the P-value if the alternative is Ha: µ > µ ? o b. What is the P-value if the alternative is Ha: µ < µ ? o c.
