A random sample of 121 bottles of cologne showed an average content of 4 ounces. It is known that the standard deviation of the contents (i. e., of the population) is 0.22 ounces. In this problem the 0.22 is Group of answer choices the standard error of the mean a parameter the average content of colognes in the long run a statistic

Standard error of the mean parameter the average content of colognes

                                S.E = 0.02 ounces                            

Step-by-step explanation:

Explanation:-

Size of random sample 'n' = 121 bottles

mean of the sample ounces

Standard deviation of Population

                      σ = 0.22

Standard error of the mean parameter the average content of colognes

                             S.E = 0.02

Final -

Standard error of the mean parameter the average content of colognes

               S.E = 0.02 ounces                            

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.
