Find the value of the test statistic )(2 . Round your answer to three decimal places. 22= the absolute tolerance is +/-0.005 Using a = 0.1, can you conclude that the current percentage distribution is different from the hypothesized one? We conclude that the current percentage distribution 4 mm the hypothesized one. is diflerent is not different
