Given two independent random samples with the following results: n1=11x‾1=80s1=28   n2=9x‾2=99s2=18 Use this data to find the 90% confidence interval for the true difference between the population means. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 3 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places
