Based on a smartphone survey, assume that 55% of adults with smartphones use them in theaters. In a separate survey of 234 adults with smartphones, it is foun hat 127 use them in theaters. a. If the 55% rate is correct, find the probability of getting 127 or fewer smartphone owners who use them in theaters. p. Is the result of 127 significantly low? a. If the 55% rate is correct, the probability of getting 127 or fewer smartphone owners who use them in theaters is Round to four decimal places as needed.) b. Is the result of 127 significantly low? than the probability cutoff that corresponds to a significant event, which v 0.5. because the probability of this event is 0.95. 0.05.
