A newspaper provided a \"snapshot\" illustrating poll results from 1910 professionals who interview job applicants. The illustration showed that 26% of them said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company. The margin of error was given as plus or minus 3±3 percentage points. What important feature of the poll was omitted?

choose the correct

1. confidence level

2. point estimate.

sample size

confidence interval

Solution

the correct alternative is confidence level.

because sample size is given as 1910

point estimate is given as 26%

margin of error is given to be +-3%

so confidence interval can be calculated using the formula [point estimate-margin or error,point estimate+margin of error]

but the confidence level at which the mrginal error is calculated is missing which is a very vital point.
