The confidence intervals is (100.86, 102.78) Calculate the mean and the margin of error. |
$\overline{x}=100.86, \,\, \mu = 101.82$ $\overline{x}=100.86, \,\, \mu = 0.96$ $\overline{x}=101.82, \,\, \mu = 0.96$ $\overline{x}=100.86, \,\, \mu =100.72$ |
$\overline{x}=101.82, \,\, \mu = 0.96$ |
The correct answer is Option (3) → $\overline{x}=101.82, \,\, \mu = 0.96$ $\bar x=\frac{\text{Lower Bound+Upper Bound}}{2}$ $=\frac{100.86+102.78}{2}=101.82$ $ME=\frac{\text{Upper Bound-Lower Bound}}{2}$ $=\frac{102.78-100.86}{2}=0.96$
