A researcher analyzed large independent samples for two groups with n_A = n_B = 1450. The 99% CI of group A mean is [127.36, 128.75]. The 99% CI of group B mean is [105.67, 107.43]. What is the margin of error for the 99% CI of the *difference* between the population means of the two groups. (Record your answer accurate to at least the nearest second decimal place with standard rounding.)

1. A researcher is comparing scores from two treatment groups using independent samples t test. Use a Hartley’s F-max test to examine this assumption (each group has 6 participants, s2 in group 1 is 20, and s2 in group 2 is 15, set alpha level at .05). Also, how should this researcher estimate the standard error in the independent samples t test?

A researcher wishes to assess how much the inclusion of a refrigerator magnet affects the response rate to direct mail for a local real estate agency. Of the 1058 mailings with a magnet, 15 homeowners contacted the agency. Of the 2600 mailings without a magnet, 25 homeowners contacted the agency. For a 95% confidence level, what is the MARGIN OF ERROR (ME) for the difference in the response rates? (Answer as a rate, not a percent. Record your answer accurate...
