Problem 7E

PROBLEM 7E

Here are the weights (in grams) of 25 indicator housings used on gauges (see Exercise 6.2-8):

(a) List the observations in order of magnitude.

(b) Give point estimates of π0.25, m, and π0.75.

(c) Find the following confidence intervals and, from Table II in Appendix B, state the associated confidence coefficient:

(i) (y3, y10), a confidence interval for π0.25.

(ii) (y9, y17), a confidence interval for the median m.

(iii) (y16, y23), a confidence interval for π0.75.

(d) Use x } tα/2(24)(s/√25 ) to find a confidence interval for μ, whose confidence coefficient corresponds to that of (c), part (ii). Compare these two confidence intervals of the middles.

References Exercise 6.2-8

The weights (in grams) of 25 indicator housings used on gauges are as follows:

(a) Construct an ordered stem-and-leaf display, using integers as the stems and tenths as the leaves.

(b) Find the five-number summary of the data and draw a box plot.

(c) Are there any suspected outliers? Are there any outliers?
