There are ...

2 + 3/4 + 1.5 + 1.25 = 5.5

cups of ingredients, and ...

1/2 + 1/2 + 3 = 4

teaspoons of ingredients. Each teaspoon is 1/3 of 1/16 of a cup, so is 1/48 of a cup.

Altogether, the volume of ingredients is ...

5.5 + 4/48 cups = 5 7/12 cups

= (5 7/12)×(240 mL/cup) = 1340 mL

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.
