A test of the breaking strength of two different types of cables was conducted using samples of n1 = n2 = 100 pieces of each type of cable. x1 = 1,930 (cable I) s1 = 39 (cable I) x2 = 1,900 (cable II) s2 = 32 (cable II) a) Do the data provide sufficient evidence to indicate a difference in the mean breaking strength of the two cables? Use ? = 0.05. State the null and alternative hypotheses. b) Find the test statistic and rejection region. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) c) state your conclusion.
