The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.8, 15.6, 15.1, 15.2, 15.1, 15.5, 15.9, 15.5 construct a 95% confidence interval for the mean amount of juice in all such bottles. assume an approximate normal distribution.a.(15.250, 15.675)b.(15.206, 15.719)c.(15.257, 15.668)d.(15.284, 15.641)e.none of the above
Accepted Solution
A:
The confidence interval is given by the formula: m +/- z·(σ/√n)
