Question

Write your answer in the p +- e notation.

A study found that out of 39,700 drivers that went through a traffic intersection, 794 ran a red light. Construct a 90% confidence interval to estimate the proportion of people who ran the light.

We will use estimation using confidence intervals. This time we will be using estimation of proportion.

x ____________

n ____________

p hat ___________

C-level ___________

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
