Using the following information:

For the first population: sample size of 30 taken from the population, sample mean 1.32 , population variance 0.9734.

For the second population : sample size of 30 taken from the population, sample mean 1.04,

population variance 0.7291.

Find a 90% confidence interval for the difference between the two population means.
