Question 1089688
<font color="black" face="times" size="3">
x = 40 is the number of successes
n = 100 is the sample size


Sample proportion
p = x/n
p = 40/100
p = 0.4


Standard Error(SE)
SE = sqrt(p*(1-p)/n)
SE = sqrt(0.4*(1-0.4)/100)
SE = <font color=red>0.04898979485567</font>


The standard error of p is approximately <font color=red>0.04898979485567</font>
