HYPZ2mean The two-sample Z-test for means. Returns a list containing (in
order):
• 0 or 1 to reject or fail to reject the null hypothesis
• The test Z-value
• The test  value
• The upper-tail probability
• The upper critical Z-value associated with the input α-level
• The critical value of  associated with the critical Z-
value
