the null hypothesis.

g.Thus, the final conclusion is that ...

• The data suggest the population proportion is notsignificantlydifferent from 19% at= 0.05, so there is statistically insignificant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 19%.
• The data suggest the populaton proportion issignificantlydifferent from 19% at= 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is different from 19%.
• The data suggest the population proportion is notsignificantlydifferent from 19% at= 0.05, so there is statistically significant evidence to conclude that the population proportion of millionaires who can wiggle their ears is equal to 19%.
