Question
Pew research asked random sample of 1000 US adults whether they supported increased usage of coal to produce energy. They found that 37% did support increase usage of coal.
In this example of a two-sided test for significance, so the hypotheses are:
H0: π = 0.5
Ha: π ≠ 0.5
In this problem, you will explore what changes if we use
π < 0.5 or π > 0.5 as our alternative hypothesis instead.
A. Produce a sampling distribution sketch, shade the area corresponding to the p value if the alternative hypothesis is
π ≠ 0.5, and find the p value.
B. In the second sampling distribution sketch, shade the area corresponding to the p value if the alternative hypothesis is
π < 0.5, and find the p value.
C. In the third sampling distribution sketch, shade the area corresponding to the p value if the alternative hypothesis is
π > 0.5, and find the p value.
