<br />
===Problem 1===<br />
We have discussed that the standard deviation of the distribution of sample percentages or SE(p hat) is calculated by taking the square root of<br />
<br />
p hat * (1 - p hat)/ N , where p hat is the proportion in the sample and N is sample size<br />
<br />
What does SE(p hat) show?<br />
<br />
*Choose one answer.<br />
<br />
:''(a) It shows the standard error of the man across repeated samples from the population.<br />
<br />
:''(b) It shows the distribution of p hat for the single sample that the researcher draws from the population.<br />
<br />
:''(c) It shows the standard deviation of p hat for repeated samples from the population.<br />
<br />
:''(d) It shows the variation for p hat values for repeated samples from the population.<br />
