Answer:

96 meatballs are required

Step-by-step explanation:

We know that the formula for he catering business is

$m=4a+2c$

Where

c= the number of children, m=the number of meat balls, a= the number of adults

So if $c = 8$ and $a = 20$ then

$m = 4(20) + 2(8)$

$m = 80 + 16$

$m = 96$

Finally 96 meatballs are required for the party

What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% conf

VARVARA [1.3K]

Answer: 271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

$n=00.25(\dfrac{z_{\alpha/2}}{E})^2$

Given : Significance level : $\alpha: 1-0.90=0.1$

By using the standard normal distribution table ,

Critical value : $z_{\alpha/2}=1.645$

Margin of error : $E=0.05$

Then , the required minimum sample size will be :-

$n=0.25(\dfrac{(1.645)}{0.05})^2=270.6025\approx271$

Hence, the required minimum sample size is 271.
