The daily intakes of milk (in ounces) for ten randomly selected children were:

23.3 28.4 10.5 16.4 26.4

18.1 20.4 17.3 27.4 13.2

Find a 98% confidence interval for the population mean μ.

Expert Solution

The formula for calculating the confidence interval for true mean of population is given by:

We have given a random sample of childrens in take of milk (in ounces) and we have to calculate the sample mean and sample standard devaition for the sample.

Critical value: For 98% confidence,

So the 98% confidence interval for the true mean daily intake of milk for children is calculated as , i.e.,
