The following are the numbers of annual tornado-related fatalities in a certain country over 2020 consecutive years: 38,42,39,47,41,36,33,40,37,29,31,25,24,22,27,30,32,35,19,2138, 42, 39, 47, 41, 36, 33, 40, 37, 29, 31, 25, 24, 22, 27, 30, 32, 35, 19, 21. Additionally, in a recent study, there were 198198 tornado fatalities among adults and 5252 among children. Assume these are random samples and test the claim that the proportion of adult fatalities is greater than 0.50.5 at the 0.010.01 significance level. What might explain the result?

Fail to reject H0 $$H_0$$ ; the sample size is too small to draw conclusions.

Problem 31Multiple Choice

The following are the numbers of annual tornado-related fatalities in a certain country over $20$ consecutive years: $38 comma 42 comma 39 comma 47 comma 41 comma 36 comma 33 comma 40 comma 37 comma 29 comma 31 comma 25 comma 24 comma 22 comma 27 comma 30 comma 32 comma 35 comma 19 comma 21$ . Additionally, in a recent study, there were $198$ tornado fatalities among adults and $52$ among children. Assume these are random samples and test the claim that the proportion of adult fatalities is greater than $0.5$ at the $0.01$ significance level. What might explain the result?

Fail to reject $H sub 0$ ; the proportion of adult fatalities is not significantly greater than $0.5$ .

Reject $H sub 0$ ; there is strong evidence to support the claim that the proportion of adult fatalities is greater than $0.5$ .

Fail to reject $H sub 0$ ; the sample size is too small to draw conclusions.

Reject $H sub 0$ ; there is strong evidence to support the claim that the proportion of adult fatalities is less than $0.5$ .
