Step-by-step explanation:

BartSMP [9]

Answer: (24.02,25.98)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : Sample size : n= 100

Sample mean : \overline{x}=25\text{ hours}

Standard deviation : \sigma=5\text{ hours}

Significance level : \alpha: 1-0.95=0.05

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

The confidence interval for population mean is given by :-

\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=25\pm(1.96)\dfrac{5}{\sqrt{100}}\\\\=25\pm0.98\\\\=(25-0.98,\ 25+0.98)=(24.02,25.98)

Hence, the 95% confidence interval for the population mean of training times is (24.02, 25.98).
