In a study to determine if taking a calcium supplement could impact the zinc concentration (mg/ml) in the blood, a doctor randomly assigned rats to two groups. One group received a dietary supplement of calcium while the other group did not. If the interest is to determine whether the mean zinc concentration in the blood differs between the two groups, specify the hypotheses being tested. (Assume normality of the underlying population distributions). Ho: The population distribution of zinc concentration (mg/ml) in the blood in the rats receiving calcium is the same as that of rats not receiving calcium. versus Ha: The population distribution of zinc concentration (mg/ml) in the blood in the rats receiving calcium is different than that of rats not receiving calcium. Ho: The population distribution of zinc concentration (mg/ml) in the blood in the rats receiving calcium is different than that of rats not receiving calcium. versus Ha: The population distribution of zinc concentration (mg/ml) in the blood in the rats receiving calcium is the same as that of rats not receiving calcium. Ho: versus Ha: Ho: versus Ha:
