A researcher is interested in seeing if negative political ads against an opponent (group one) are more persuasive than positive ads for an original candidate (group two). She creates a scale to measure how persuasive the ads are; larger numbers mean more persuasive. She collects the following data (write these numbers down; they don't appear on the followup questions): • Group One (Negative ads): ₁ = 7.08, s² = 2.79, n₁ = 20 • Group Two (Positive ads): ₂ = 9.44, s² = 4.8, n₂ = 20 What is the t-statistic for this test? (Write your answer below, to two decimal places as a positive value; sign doesn't matter)
