Question

question 6 1 pts six researchers each survey a random sample of 100 customers at a local grocery store in order to estimate the percentage of customers who typically pay for their groceries with cash. the sample percentages obtained by the six researchers are as follows: 11%, 11%, 10%, 12%, 10%, and 9%. it turns out the true population percentage is 15%. these six sample results illustrate a little bias and negligible variability. large bias and small variability. negligible bias and large variability. large bias and large variability. small bias and unusually large variability.

Explanation:

Bias is the difference between the sample - based estimate and the true population value. Here, the sample percentages (11%, 11%, 10%, 12%, 10%, 9%) are all lower than the true population percentage of 15%, showing a consistent under - estimation, which means large bias. Variability is the spread of the sample statistics. The sample percentages are relatively close to each other, indicating small variability.

Answer:

B. large bias and small variability
