When we assume the null hypothesis is true, and a p < .05 criteria for statistical significance, what do we know about the shape, center, spread, and critical values in the sampling distribution?
Shape: The shape of the distribution is
Center: The most frequent \(\mu\) is equal to the known population average.
Spread: The \(\sigma_{\bar{x}}\) is equal to the known population standard deviation divided by the
$Z_{crit}$ values: \(\pm\) 3 decimal places
