She places a group of lizards at 25C and another group of lizards at 15C, lets them breed, and then counts the number of male and female lizards produced at each temperature. What statistical test should she use to analyze her data? Chi-Squared Goodness of Fit Chi-Squared Test for Independence t-test ANOVA Linear regression A researcher is testing a new pain killer called "OUCH". The gives various doses to rats and then measures how long they will stand on a warm hot plate before they get off the hot plate. He obtains the data below. He wants to know if there is a simple dose-dependent response of the rats to the pain killer. What statistical test should he use to analyze the data?
