A recent study was conducted on cartwheels and it found that only about 17% of all people can do a cartwheel. Is this percent higher for millionaires? There were 380 millionaires surveyed and 80 could do a cartwheel. What can be concluded at the a = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer v (please enter a decimal) H1: ? vSelect an answer (Please enter a decimal) c. The test statistic ? v (please round your answer to 3 decimal places.) %3D d. The p-value = (Please round your answer to 3 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the populaton proportion is significantly higher than 17% at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can do a cartwheel is higher than 17%. O The data suggest the population proportion is not significantly higher than 17% at a = 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can do a cartwheel is equal to 17%. O The data suggest the population proportion is not significantly higher than 17% at a = 0.05, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can do a cartwheel is higher than 17%.

Transcribed Image Text:A recent study was conducted on cartwheels and it found that only about 17% of all people can do a
cartwheel. Is this percent higher for millionaires? There were 380 millionaires surveyed and 80 could do a
cartwheel. What can be concluded at the a = 0.05 level of significance?
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)
H1: ? v Select an answer v
(Please enter a decimal)
c. The test statistic ? v
(please round your answer to 3 decimal places.)
d. The p-value =
(Please round your answer to 3 decimal places.)
e. The p-value is ? v a
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the populaton proportion is significantly higher than 17% at a = 0.05, so
there is statistically significant evidence to conclude that the population proportion of
millionaires who can do a cartwheel is higher than 17%.
O The data suggest the population proportion is not significantly higher than 17% at a = 0.05, so
there is statistically significant evidence to conclude that the population proportion of
millionaires who can do a cartwheel is equal to 17%.
O The data suggest the population proportion is not significantly higher than 17% at a = 0.05, so
there is statistically insignificant evidence to conclude that the population proportion of
millionaires who can do a cartwheel is higher than 17%.
