In 2016, the US poverty rate was 12.7%. During that year, 375 families where randomly selected in Hawaii. Out of them, 23 were found to be living below the poverty line. At a level of significance of a 0.01, do the data provide sufficient evidence to conclude that, in 2016, the percentage of families below the poverty line was lower in Hawaii than among all US families? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer v (please enter a decimal) H ? v Select an answer v (Piease enter a decimal) C. The test statistic ? ♥ = |(please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should reject v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly lower than 12.7% at a = 0.01, so there is not sufficient evidence to conclude that the population proportion of Hawaiian families who are below the poverty line is lower than the US as a whole. O The data suggest the population proportion is not significantly lower than 12.7% at a = 0.01, so there is sufficient evidence to conclude that the population proportion of Hawaiian families who are below the poverty line is lower than the US as a whole.

Transcribed Image Text:In 2016, the US poverty rate was 12.7%. During that year, 375 families where randomly selected in
Hawaii. Out of them, 23 were found to be living below the poverty line. At a level of significance of a
= 0.01, do the data provide sufficient evidence to conclude that, in 2016, the percentage of families
below the poverty line was lower in Hawaii than among all US families?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: ? v Select an answer v
(please enter a decimal)
H ?v Select an answer v
(Please enter a decimal)
C. The test statistic | ? ♥
|(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is[? v a
f. Based on this, we should i
reject
v the null hypothesis.
g. Thus, the final conclusion is that ..
O The data suggest the population proportion is not significantly lower than 12.7% at a =
0.01, so there is not sufficient evidence to conclude that the population proportion of
Hawaiian families who are below the poverty line is lower than the US as a whole.
O The data suggest the population proportion is not significantly lower than 12.7% at a
0.01, so there is sufficient evidence to conclude that the population proportion of
Hawaiian families who are below the poverty line is lower than the US as a whole.
