The quality control engineer for a furniture manufacturer is interested in the mean amount of force necessary to produce cracks in stressed oak furniture. she performs a two-tail test of the null hypothesis that the mean for the stressed oak furniture is 650. the calculated value of the z test statistic is a positive number that leads to a p-value of 0.080 for the test. true or false: suppose the engineer had decided that the alternative hypothesis to test was that the mean was less than 650. then if the test is performed with a level of significance of 0.05, the null hypothesis would be rejected.
