Boxes of cereal are labeled as containing 14 ounces. Following are the weights, in ounces, of a sample of 12 boxes. It is reasonable to assume that the population is approximately normal. 13.03 14.98 13.12 13.13 13.11 13.03 13.16 14.98 13.06 13.05 13.12 13.13 2. Sand data Part: 0/2 WS Part 1 of 2 (a) Construct a 95% confidence interval for the mean weight. Round the answers to at least three decimal places. A 95% confidence interval for the mean weight is

95% Confidence interval:  (12.93, 13.87)      

Step-by-step explanation:

We are given the following in the question:

13.03, 14.98, 13.12, 13.13, 13.11, 13.03, 13.16, 14.98, 13.06, 13.05, 13.12, 13.13

Formula:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences = 5.94

95% Confidence interval:  

Putting the values, we get,  

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.
