Answer:
327
Step-by-step explanation:
Calculation for How large of a sample would be required in order to estimate the mean per capita income
First step is to find z 80% confidence level
At 80% confidence level the z will be:
α/2 = 1 - 80% = 1 - 0.80 = 0.20
α/2= 0.20 / 2 = 0.01
Zα/2= Z0.01= 1.28 from z table
Now let calculate the Sample size using this formula
Sample size = n= [( Zα/2* σ ) / E]^2
Let plug in the formula
n = (1.28*7.9/0.56)^2
n= 326.06
n=327 (Approximately)
Therefore How large of a sample would be required in order to estimate the mean per capita income will be 327
3 to 4.....added = 7
3/7x = 210....3/7 of all factory workers (x) are men...and men = 210
x = 210 * 7/3
x = 1470/3 = 490...so there is 490 factory workers
4/7(490) = 1960/7 = 280...and there are 280 women....because 4/7 of all factory workers are women

Answer:
Step-by-step explanation:
There are total 300 pieces of candy.
Adrian gets 1/4 of total
<u>Multiply the total number by 1/4, to find the number Adrian gets:</u>
Darien gets 10% of total.
<u>10% is equal to 10/100 = 1/10. Multiply 300 by 1/10 to get the number Darien gets:</u>
