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
