The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution.
Test $H_0: \mu = 75$ vs $H_a: \mu > 75$ when the sample has $n = 22, \bar{x} = 82.4$, and $s = 3.5$ with $SE = 0.7$.
Find the value of the standardized z-test statistic.
Round your answer to two decimal places.
$z = $
