To test upper h 0 : sigma equals 60 versus upper h 1 : sigma less than 60, a random sample of size n equals 25 is obtained from a population that is known to be normally distributed. (a) if the sample standard deviation is determined to be s equals 51.6, compute the test statistic. (b) if the researcher decides to test this hypothesis at the alpha equals 0.01 level of significance, use technology to determine the p-value. (c) will the researcher reject the null hypothesis?

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
