If the 45% rate is correct, the probability of getting 94 or fewer smartphone owners who use them in theaters is ___. Is the result of 94 significantly low? ___, because the probability of this even is ____ than the probability cutoff that corresponds to a significant event, which is ___ (Yes, No) (Greater, Less) (.5, 0.05, 1)
