A random sample of 2000 citizens are asked whether they support the Government’s Foreign Policy or not? 58% of the respondents expressed support, while the rest 42 % were against. Calculate :
3.1.a the Mean support for Government’s Foreign Policy (if Support=1 Against=0)
3.1.b The Standart Deviation of the Sample is equal to 5.0. Calculate the Standart Error of the Sample mean ) (i.e. δ ȳ )
3.1.c Determine the upper and lower boundaries of the popular support for Government’s Foreign policy in the population (the confidence interval at %5 risk level )
3.1.d Determine the upper and lower boundaries of the popular support for Government’s Foreign policy in the population (the confidence interval at %1 risk level )
