Answer: The confidence level

Step-by-step explanation:

We are given that a newspaper provided a​ "snapshot" illustrating poll results from 1910 professionals who interview job applicants.

i.e. We are given sample size of 1910.

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.

i.e. sample proportion: [tex]\hat{p}=0.26[/tex]

We have point estimate for population proportion . [∵ Sample proportion is considered as the best estimate for population proportion. ]

The margin of error was given as plus or minus 3 percentage points.

But to measure the Margin of error we require Confidence leveel too, which is missing.

Hence, the important feature of the poll was​ omitted = The confidence interval
