Answer: ($3.532, $4.166)

Step-by-step explanation:

Given : Significance level : $\alpha: 1-0.90=0.10$

Critical value : $z_{\alpha/2}=1.645$

Sample size : n= 157

Sample mean : $\overline{x}=\$\ 3.849$

Standard deviation : $\sigma= \$\ 2.421$

The confidence interval for population mean is given by :_

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$\text{i.e. }\$\ 3.849\pm (1.64)\dfrac{2.421}{\sqrt{157}}\\\\\approx\$\ 3.849\pm0.317\\\\=(\$\ 3.849-0.317,\$\ 3.849+0.317)=(\$\ 3.532,\$\ 4.166)$

Hence, the 0% confidence interval for the average tip given at this restaurant = ($3.532, $4.166)
