The wirney found that 67% feel engaged, and the 95% confidence interval for the proportion that feel engaged was (0.62,0.72) : Which of the following sources of error are accounted for by the contidence interval? (Select all that apply.) Non-response bias is present since some of the seiected employees didnt recpond. Response blas is present since some employees lied, giving responses that they think their supervisors want to hear. Sample percentages vary from sample to sample, se they are not perfect estimates of the population percentage who fee angaged ot werk.

Answer 1

The confidence interval accounts for sampling error and non-response bias, but not for response bias.

Step-by-step explanation:

The confidence interval accounts for sampling error, which is the natural variability in sample percentages from sample to sample. This means that the confidence interval takes into consideration that the proportion of engaged employees may vary slightly in different samples. Non-response bias is also accounted for, as the employees who did not respond are considered in the confidence interval. However, response bias, which refers to employees lying or giving responses they think their supervisors want to hear, is not directly accounted for in the confidence interval.
