The standard deviation of pulse rates of adult males is more than 11 beats per minute. This is a claim about a population proportion so a normal distribution is assumed. The claim undergoes a hypothesis test using a significance level of α = 0.05. The P-value based on sample data is calculated to be 0.345.

1.  State the null and alternative hypothesis.

2.  What kind of test would this be - two-tailed, left-tailed or right-tailed?

3.  Sketch a normal distribution curve and highlight the region of significance.  On the graph, highlight the P-value.

4.  State a conclusion about the null hypothesis (reject or fail to reject H0).
