whats wrong with expressing hypotheses about proportions and means in a form such as Ho:p^= .50 and Ho: x=0 ?
Solution
The hypothesis is always about population proportion and p^ denotes sample proportion while p denotes population proportion. Therefore, the correct hypothesis should be Ho:p=0.50.
Also the hypothesis is always about population mean and x denotes sample mean while denotes population mean. Therefore, the correct hypothesis should be Ho:=0.
