You measure the lifetime of a random sample of 64 tires of a certain brand. The sample mean is x¯=50 months. Suppose that the li

Answer:

(48.3875, 51.6125)

Step-by-step explanation:

At 99% level of significance

$\alpha=1-0.99=0.01$

$Z_{a\lpha /2}=0.01/2=0.005$

From the normal standard deviation table $Z_{a\lpha /2}=2.33$

Considering that

$\bar x$ ± $Z_{a\lpha /2} \frac {\sigma}{\sqrt{n}}$ =50± $2.33\frac {5}{\sqrt {64}}$

50±2.33(0.625)=50±1.6125=(48.3875, 51.6125)

Therefore, there’s 99% confidence that the mean lifetime of a certain brand of tires is between 48.3875 and 51.6125
