- Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 11 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x = 3.15 grams. Based on previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with ? = 0.22 gram. (b) What conditions are necessary for your calculations? (Select all that apply.) ? is known n is large uniform distribution of weights ? is unknown normal distribution of weightsYou believe both populations are normally distributed, but you do not know the standard deviations for either. And you have no reason to believe the variances of the two populations are equal You obtan a sample of size nį = 25 with a mean of 1 population. You obtain a sample of size n2 s2 = 13.9 from the second population. 63.7 and a standard deviation of s = 13.2 from the first 19 with a mean of g 67 and a standard deviation ofI need the answer as soon as possible
