5) 0.1221.

0.628

Step-by-step explanation:

Probability of U.S. smartphone owners have made an effort to limit their phone use in the past : p = 0.4702

Sample size : n= 54

Mean :

Standard deviation:

The probability that between 22 and 29 (inclusively) will have attempted to limit their cell phone use in the past will be :

Hence, the required probability = 0.628
