Answer: 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 : $\mu =(54)(0.4702)=25.39$

Standard deviation:

$\sigma=\sqrt{(54)(0.4702)}=\sqrt{25.39}\\\\\approx5.039$

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

$P(22\leq x\leq29)=P(21$

Hence, the required probability = 0.628
