At 95% confidence, how large a sample should be taken to obtain a margin of error of .03 for the estimation of the population proportion? assume past data are not available for developing a planning value for p*.

The sample should be 1,068.

Step-by-step explanation:

Consider the provided information.

Confidence level is 95% and margin of error is 0.03.

Thus,

1-α=0.95

α=0.05, E=0.03 and planning value

Formula to calculate sample size is:

From the table we can find:  

Substitute the respective values in the above formula we get:

Hence, the sample should be 1,068.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

is means division by fractions
