Answer
143.52 < $\mu$ < 156.48$
The CI is wider in this question.
Work Step by Step
Formula for CI
$\bar{x}$ $\pm$ ( z$\times$$\frac{\sigma}{\sqrt n}$)
=$150 \pm ( 2.5758\times\frac{19.50}{\sqrt60 })$
= $150\pm 6.484$
CI: $143.516 < \mu < 156.484 \approx 143.52 < \mu < 156.48$
The CI is wider in this question. This is because the higher standard deviation indicates that there is more variability in this population.
