Answer:
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>
<em>(2.91562, 3.04438)</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the size of the sample 'n' = 10
Given that the mean of the sample (x⁻) = 2.98
Given that the standard deviation of the sample (s) = 0.09
Degrees of freedom = n-1 = 10 -1 = 9
t₀.₁₀ = 2.2621
<u><em>Step:2</em></u>
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>
(2.98 - 0.06438 , 2.98 + 0.06438)
(2.91562 , 3.04438)
<u><em>Final answer:-</em></u>
<em>The 90% confidence interval for the population mean length of nails produced by the machine.</em>
<em>(2.91562, 3.04438)</em>
