Question 4 (Choose the correct answer)

Extracted text: Let X1, X2, ..X100 be 100 independent observations from a distribution X which is not normally distributed. Suppose it is known that the mean of this distribution X is 26 and the standard deviation is 6. What can we say about the sample mean x? O a x has an approximately normal distribution with mean=26 and standard deviation=6 O b x has an approximately normal distribution with mean=26 and standard deviation=0.6 None of the other answers x cannot be approximated with a normal distribution since X is not normal O e X = 2.6
