Employ the given degree of confidence and sample data to construct a confidence interval for the population mean? Assume that the population has a normal distribution.
The amounts (in ounces) of juice in eight randomly selected juice bottles are:
15.2 15.5 15.9 15.5
15.0 15.7 15.0 15.7
Construct a 98% confidence interval for the mean amount of juice in all such bottles.
