An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in Texas. He believes that
nadezda [96]

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

nexus9112 [7]
3 to 4.....added = 7

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

wel

Answer:

  • 170 pieces left

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>

  • 300*1/4 = 75

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>

The little brother gets 25 pieces.

<u>Number of pieces Jordan has given:</u>

  • 75 + 30 + 25 = 130

<u>Number of pieces left:</u>

  • 300 - 130 = 170 pieces
