Consider the following results for independent random samples taken from two populations. Sample 1 Sample 2 n 1 = 20 n 2 = 40 x 1 = 22.2 x 2 = 20.2 s 1 = 2.3 s 2 = 4.8 What is the point estimate of the difference between the two population means (to 1 decimal)? What is the degrees of freedom for the t distribution (round down your answer to nearest whole number)? At 95% confidence, what is the margin of error (to 1 decimal)? What is the 95% confidence interval for the difference between the two population means (to 1 decimal)? Use z-table. If your answer is negative value, entre minus (-) sign

x 1 = 22.2 | x 2 = 20.2 |
s 1 = 2.3 |
s 2 = 4.8 |
