Answer: 196

Step-by-step explanation:

As per given , we have

Population standard deviation: $\sigma=0.6\ lb$

Significance level : $\alpha: 1-0.98=0.02$

Using the z-value table , the critical z value for 98% confidence : $z_{\alpha/2}=2.33$

Margin of error : E= 01 lb

Sample size : $n=(\dfrac{z_{\alpha/2}\cdot\sigma}{E})^2$

$n=(\dfrac{(2.33)\cdot(0.6)}{0.1})^2$

Simplify , we get

$n=195.4404\approx196$

Hence, the minimum sample size required for books = 196
