 a. State the appropriate null and alternative hypotheses for testing whether one-third of all adult Americans would answer “always.” 

b. Check and comment on whether the technical conditions for conducting this test are satisfied. The sample result was that 304 of the 977 people responded “always.” 

c. Calculate the value of the test statistic.

 d. Calculate the p-value. 

e. Interpret what this p-value means in this context. [Hint: The p-value is the probability of what, assuming what?] 

f. State your test decision at the α  .05 significance level. 

g. Summarize your conclusion in the context of this study
