The volume of nectar produced by flowers in two plant species was measured across a rainfall gradient. A linear regression model was constructed for each species with nectar volume as a function of rainfall {measured in cm per year}. For both species, the volume of nectar produced by the plants increased with increasing rain, which was reflected by both species having positive slopes that were significantly different from zero. You need to compare the slopes from the two plant species to test the null hypothesis that the slope of Species A equals the slope of Species B. You should assu me that the two species have equal variance. The pooled variance 52 has been calculated for you and equals 0.0922. The following information is also provided: Species A Slope = 0.632 SSX = 159 n {number of observations] = 22 Species B Slope = 0.749 SSX = 148 n {number of observations] = 22 What is T-calculated to compare the slopes?What is T-critical to compare the slopes?Question 28:-Complete the hypothesis test, what is your conclusion?
