To understand your competitive position, you have examined the reliability of your product as well as the reliability of your closest competitor’s product. You have subjected each product to abuse that represents about a year’s worth of wear and tear per day. Table 16.4.6 gives the data indicating how long each item lasted.
a. Find the median time to failure for your and your competitor’s products. Find the difference in medians (subtracting the smaller from the larger).
b. Find the nonparametric test statistic to determine whether your reliability differs significantly from your competitor’s.
c. State the result of this nonparametric test.
d. Write a brief paragraph, complete with footnote(s), that might be used in an advertising brochure showing off your products.
