A survey of 750 voters in one state reveals that 308 favor approval of new signs on the highway exits. Construct a 95% confidence interval for the proportion of all voters in the state who favor approval of the new signs.

See attachment below and find the equivalent of tan(∠qsr)

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.
