For conducting a two-tailed hypothesis test with a certain data set, using the smaller of n11 and n21 for the degrees of freedom results in df11, and the corresponding critical values are t2. 201. Using the formula for the exact degrees of freedom results in df19. 063, and the corresponding critical values are t2. 93. How is using the critical values of t2. 201 more "conservative" than using the critical values of 2. 093?.

Nathan is an ecologist. he’s studying the effect of secondary consumers on primary consumers. his current research focuses on a population of blue jays and crows. they eat caterpillars and mice. if the number of blue jays increases, what are the likely effects on other populations? 1the number of crows will increase. 2the number of mice will decrease. 3the number of mice will remain the same. 4the number of caterpillars will decrease.
