1. Find the sample size, mean, variance and standard deviation.
2. Assume GDP growth rate follows standard normal distribution. Now using Z-table, find the probability that the future GDP growth rate would be less than 6.50.
3. Using the same Z-table, find the probability that the future GDP growth rate would be greater than 2.
4. Find the range of GDP growth rate using 95% confidence level. Interpret the result.
