If the 56% rate is correct, find the probability of getting 123 or fewer smartphone owners who use them in theatersb. Is the result of 123 significantly low?a. If the 56% rate is correct, the probability of getting 123 or fewer smartphone owners who use them in theaters is 0.0530(Round to four decimal places as needed.)

We have given that Sample size n =22 Population proportion p=56%=0.56
