PROBLEM 9E

Let X equal the amount of fluoride in a certain brand of toothpaste. The specifications are 0.85– 1.10mg/g. Table 6.1-3 lists 100 such measurements.

Reference Table 6.1-3

(a) Give a point estimate of the median m = π0.50.

(b) Find an approximate 95% confidence interval for the medianm. If possible, use a computer to find the exact confidence level.

(c) Give a point estimate for the first quartile.

(d) Find an approximate 95% confidence interval for the first quartile and, if possible, give the exact confidence coefficient.

(e) Give a point estimate for the third quartile.

(f) Find an approximate 95% confidence interval for the third quartile and, if possible, give the exact confidence coefficient.
