Answer #1

A random sample of n=53 engineering students at KAU is selected, 30 of them found to support exit.

Therefore, the estimate of the population proportion is

The maximum error of the estimation at 96% confidence for the proportion of engineering students favouring the exit given by:

By using z table z0.05=2.05 ## taking absolute value

Therefore, the maximum error of estimation is E=0.1390
