12. Two independent samples are taken from two populations. Sample 1 has a mean of 12.8, astandard deviation of 2.3, and a sample size of 18. Sample 2 has a mean of 14.2, a standarddeviation of 5.2, and a sample size of 23. This gives a standard error se(Ã1 — Ă2) = 1.212.A 95% confidence interval for the difference between the two means is:(A) (-2.00, -0.80).(B) (11.66, 13.94).(C) (-3.96, 1.16).(D) (-3.85, 1.05).(E) (-3.78, 0.98).

It is given that sample means are 12.8 and 14.2.

A researcher has obtained the following scatter plot depicting the relationship between Y and X. On the graph, you can see three possible regression lines, which have a common y-intercept of bo = 35.48. Lines A, B and C cross the y-axis at coordinates (52, 106.78), (52, 66.52) and (52, 36.67), respectively.
