- Based on this p value can we reject the null hypothesis??Pose a null and alternate hypothesis for a two sample t-test using variables: Male and Female, Asthma, number of injuries, or flu shot. Can any of the variables also be used to do a Chi square test or a NOVA test?Which is the correct null hypothesis based on this statement: People with diabetes have higher systolic blood pressure than people without diabetes? People with diabetes have lower systolic blood pressure than people without diabetes. People with diabetes have equal systolic blood pressure when compared to people without diabetes. People with diabetes have a systolic blood pressure equal to or lower than people without diabetes. None of these are a null hypothesis.
