Question Answered step-by-step In a population, the mean is known to be 1.78 and the standard… In a population, the mean is known to be 1.78 and the standard deviation is known to be 0.190. Suppose a random sample of size 100 is taken from this population. What can be said about the distribution of the sample mean? Select one:It is approximately normal, with mean 1.78 and standard deviation 0.002It is approximately normal, but with unknown mean and unknown standard deviation.It is approximately normal, with mean 1.78 and standard deviation 0.060.It is approximately normal with mean 1.78, but the standard deviation is not known.It is approximately normal, with mean 1.78 and standard deviation 0.190.It is approximately normal, with mean 1.78 and standard deviation 0.019.There is not enough information to say anything about this distribution.    Math Statistics and Probability M 140 Share QuestionEmailCopy link Comments (0)
