1) For the given sample data and nullhypothesis, compute the value of the teststatistic, z. Round your answer to two decimal places.

The claim is that the proportion of drowning deaths of children occurring at beaches is more than 0.25. The sample statistics include n equals 615 drowning deaths of children with30% of them occurring at beaches.

A. 2.86

B. 0.25

C. 2.71

D. 2.71

E. 2.86

2) A journal article reports that34% of American fathers take no responsibility for child care. A researcher claims that the figure is higher for fathers in a particular town. A random sample of 233 fathers from this town yielded 96 who did not help with child care. Do the data provide sufficient evidence to conclude that in this town the proportion is higher than0.34? Use a 0.05 significance level. The hypotheses are Upper H 0

H0: p = 0.34 and Upper H Subscript a

Ha: p > 0.34, the test statistic is z=2.32, and theP-value is 0.0102. State your conclusion in terms of Upper H 0

A. Since the P-value < , we can conclude that the proportion of fathers who take no responsibility for childcare is higher than34% in this town.

B. Since the P-value <0.34, we can conclude that the proportion of fathers who take no responsibility for childcare is higher than34% in this town.

C. Since the P-value <, we can conclude that the proportion of fathers who take no responsibility for childcare is41%.

D. Since the P-value <0.34, we are unable to conclude that the proportion of fathers who take no responsibility for childcare is higher than34% in this town.

E. Since the P-value< , we are unable to conclude that the proportion of fathers who take no responsibility for childcare is higher than34% in this town.
