Question

28 B. Is the result of 158 significantly low? Fill in blank Yes or no because the probability of this event is less or greater than the probability cut off that corresponds to a significant event which is 0.5 or 0.05 or 0.95

Based on a smartphone survey, assume that 56% of adults with smartphones use them in theaters. In a
separate survey of 289 adults with smartphones, it is found that 158 use them in theaters.
a. If the 56% rate is correct, find the probability of getting 158 or fewer smartphone owners who use them in
theaters.
b. Is the result of 158 significantly low?
a. If the 56% rate is correct, the probability of getting 158 or fewer smartphone owners who use them in
theaters is
(Round to four decimal places as needed.)
b. Is the result of 158 significantly low?
V because the probability of this event is
V than the probability cutoff that corresponds to a
significant event, which is
