3. As part of an agreement with the Johnson wire company, only 1% or less of incoming spools of wire can fail a strength test. Out of the 400 most recent spools of wire, 6 have failed the strength test. Use a hypothesis test with a significance level of 0.05 to determine if the Johnson company still living up to the agreement. is Write your null and alternative hypotheses next to Ho and Ha on the Excel sheet. Use <= or >= for less than or equals or greater than or equals wherever you need them in the hypotheses. Write 'xbar' for any sample means and 'pbar' for any sample proportions that you use, e.g. 'xbar' for x and 'pbar' for p as in H, : pbar >=.34 H, : pbar <.34
