5. On a paper. A random sample of n = 1400 observations from a binomial population produced
x = 529.
1. If your research hypothesis is that p differs from 0.4, what are the null and alternative hypotheses?
2. Calculate the test statistic and its p-value. Use the p-value to evaluate the statistical significance of
the results at the 1% level. 
3. Do the data provide sufficient evidence to indicate that p is different from 0.4? Answer in a complete
sentence (i.e., not just ”yes” or ”no”).
