To assess attitudes towards issues that affect the residents of a village, the village randomly chose 800 families to participate in a survey of life attitudes. The village received 628 completed surveys. What is the sample proportion of completed surveys?

The sample proportion of completed surveys is 0.785 = 78.5%.

Step-by-step explanation:

The sample proportion of completed surveys is the number of completed surveys divided by the total number of surveys.

We have that:

800 families, so 800 total surveys

Proportion

The sample proportion of completed surveys is 0.785 = 78.5%.

$649.60
