a)
p-value = 2 * P(Z > z)
= 2 * P(Z > 2.03)
= 2 * 0.0212
= 0.0424
b)
p-value = 2 * P(Z > z)
= 2 * P(Z > 1.50)
= 2 * 0.0668
= 0.1336
c)
p-value = 2 * P(Z > z)
= 2 * P(Z > 1.40)
= 2 * 0.0808
= 0.1616
d)
p-value = 2 * P(Z > z)
= 2 * P(Z > 2.26)
= 2 * 0.0119
= 0.0238

Which of the following statements are true regarding one sided and two slded hypothesis tests? There are two correct answers; you must select both correctly. For this problem, you have five tries. Note: you should assume that a one sided test is not being performed on the 'wrong side. For example, if the test statistic is positive, then assume the test is right sided and not left sided. Hint: you should consider what happens to the p-value when going from...
