95% confidence interval is:
sample mean +/- z-critical * standard deviation/sqrt(sample size)
sample mean is given as 50, standard deviation given as 10 and sample size is given as 60
z-critical for 95% confidence interval is 1.96.

A local newspaper in a large city wants to assess support for the construction of a highway bypass around the central business district to reduce downtown traffic. They survey a random sample of 1152 residents and find that 543 of them support the bypass. Construct and interpret a 95% confidence interval to estimate the proportion of residents who support construction of the bypass.
