In a recent survey, 10 percent of the participants rated Pepsi as being "concerned with my health." PepsiCo's response included a new "Smart Spot" symbol on its products that meet certain nutrition criteria, to help consumers who seek more healthful eating options. At α = .05, would a follow-up survey showing that 18 of 100 persons now rate Pepsi as being "concerned with my health" provide sufficient evidence that the percentage has increased?
a. No, it would not since we reject the null hypothesis at α=0.05 significance level.
b. Yes, it would since we reject the null hypothesis at α= 0.05 significance level.
c. No, it would not since we fail to reject the null hypothesis at α=0.05 significance level.
