A 2006 Gallup Poll found that 40 percent of American adults say they attended religious services last week. This is almost certainly not true.

You suspect strongly that the true percentage attending church in any given week is less than 40 percent. You plan to watch a random sample of adults and see whether or not they go to church.
Identify the alternative hypothesis (p=0.4 or p<0.4 or p not =0.4)
Part two: Suppose the P value of a hypothesis test was 0.02 and the level of significance (alpha) was 0.05. What is the correct decision? (there is not enough evidence to find in favor of Ho, there is enough evidence to find in favor of HA or there is enough evidence to find in favor of HA)?
