Antonia read an article that said 26% of Americans can speak more than one language. She was curious if
this figure was higher in her city, so she tested H, :p=0.26 vs. H, :p > 0.26, where p represents the
proportion of people in her city that can speak more than one language.
Antonia took a sample of 120 people in her city found that 35% of those sampled could speak more than
one language. The test statistic for these results was z ~ 2.25, and the corresponding P-value was
approximately 0.01. Assume that the conditions for inference were met.
Is there sufficient evidence at the a= 0.05 level to conclude that the proportion of people in her city
that can speak more than one language is greater than 26%?
