(please show your answer to 3 decimal places.)
(Please show your answer to 3 decimal places.)
O The data suggest the population proportion is not significantly different from 15% at a = 0.10,
so there is statistically significant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is equal to 15%.
O The data suggest the population proportion is not significantly different from 15% at a = 0.10,
so there is statistically insignificant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is different from 15%.
O The data suggest the populaton proportion is significantly different from 15% at a = 0.10, so
there is statistically significant evidence to conclude that the population proportion of
millionaires who can wiggle their ears is different from 15%.
