A Computer Laboratory Manager Was Interested in Whether There Was

Short Answer

A computer laboratory manager was interested in whether there was a difference in functioning time before needing to be recharged for three battery packs for laptop computers. The manager took a random sample of six battery packs of each brand and tested them. The results, in hours of functioning before needing to be recharged, were recorded as The manager, unsure that the assumptions for the usual parametric analysis of variance were valid, decided to employ nonparametric methods. Use the appropriate nonparametric procedure to determine whether the distribution of functioning time before needing to be recharged is the same for the three brands of battery packs. Use = 0.05.
Test Statistic:
H = ______________
What is the critical value for the test statistic?
Reject if the test statistic > ______________.
Conclude: ______________
There ______________ sufficient evidence at = 0.05 to say that at least two of the distributions of functioning times before battery needing to be recharged differ in location.
