Answer:

ab = 21

Step-by-step explanation:

$(a - b)^2 = (a^2 + b^2 ) - 2ab\\\\4^2 = 58 - 2ab\\\\16 - 58 = - 2ab\\\\- 42 = - 2ab\\\\ab = \frac{-42}{-2} = 21$

Answer: 0.0433

Step-by-step explanation:

Given: Sample size : n= 133

The number of females in sample = 65

Then the proportion of females : $P=\dfrac{65}{133}$

The formula to calculate the standard error of the proportion is given by :-

$S.E.=\sqrt{\dfrac{P(1-P)}{n}}$

$\Rightarrow S.E.=\sqrt{\dfrac{\dfrac{65}{133}(1-\dfrac{65}{133})}{133}}\\\\\Rightarrow\ \Rightarrow S.E.=0.0433444676341\approx0.0433$

Hence, the standard error of the proportion of females is 0.0433.
