Collects evidence against H, (evidence against the assumption) (evidence for the researcher's belief) (evidence for the assumption) b. Collects evidence for Ha c. Collects evidence for H, с. d. Both a and b. 29. What is true about t distributions? Hint: See p 413 a. There is more than onet distribution (i.e. more than one t density curve) and they are all symmetric and centered at 0. b. As sample size increases, the t density curve…
