刚面完。答的不咋样。
1. suppose four colors are there, we did a survey. People (n) choose
different colors (red, green, yellow, blue).
we get the proportion of people who use red as x1/n.
What is the accuracy for this?
2. Imaging now that we know from prior studies that a certain proportion of
users responds to questions randomly. How can we assess this proportion of "
random clickers"?
