A bag contains 25 balls 20 of which are blue what percentage of balls are not blue

Artist 52 [7]

Answer:

20%

Step-by-step explanation:

20/25 = blue

This means 5/25 of the balls in the bag are NOT blue

(25-20 = 5)

We need to convert 5/25 to a percentage

$\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}$

% = per cent

"per" means "out of"

"cent" means "one hundred"

20/100 = 20%

In a prior sample of corn, farmer Carl finds that 14% of the sample has worms but the margin of error for his population estimat

Savatey [412]

Answer: 741

Step-by-step explanation:

As per given ,we have

The prior estimate of population proportion: $p=0.14$

Margin or error : 2.5%=0.025

Critical value for 95% confidence = $z_{\alpha/2}=1.96$

Formula to find the sample size :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

i.e. $n=0.14(1-0.14)(\dfrac{1.96}{0.025})^2$

$=740.045824\approx741$

Hence, the minimum sample size required to obtain this type of accuracy= 741
