In a random sample of 60 dog owners enrolled in obedience training, it was determined that the mean amount of money spent per ow

Anton [14]

Answer: $(\$106.29,\ \$112.37)$

Step-by-step explanation:

Given : Sample size : $n=60$

The mean amount of money spent per owner = $\$109.33\text{ per class}$

Standard deviation : $\sigma=\$12$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

We know that the confidence interval for population mean is given by :-

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

$109.33\pm(1.96)\dfrac{12}{\sqrt{60}}\\\\\approx109.33\ \pm\ 3.04\\\\\approx(109.33-3.04,\ 109.33+3.04)\\\\(106.29,\ 112.37)$

Hence, the 95% confidence interval for the mean amount spent per owner for an obedience class will be $(\$106.29,\ \$112.37)$
