Jet001 [13]

Answer:

80.0456<\bar x<81.1210

Step-by-step explanation:

-Given the mean, \bar y=80.5833 and s=2.77369, the confidence interval can be calculated using the formula:

\bar x\pm z\times \frac{\sigma}{\sqrt{n}}

#We substitute our values in the formula to solve for CI:

=\bar x\pm z\times \frac{\sigma}{\sqrt{n}}\\\\=\bar y\pm z_{0.05}\times \frac{s}{\sqrt{72}}\\\\=80.5833\pm 1.645\times \frac{2.77369}{\sqrt{72}}\\\\=80.5833\pm0.5377\\\\=[80.0456,81.1210]

Hence, the confidence interval lies between 80.0456 and 81.1210
