- Let the random variable X follow a distribution with a mean of
μ and a standard deviation of σ. Let X1 be the mean of a sample of
n1 (n1=1) observations randomly chosen from
this population, and X2 be the mean of a sample of n2(
n2 =49) observations randomly chosen from the same
population. Which of the following statement is False? Evaluate the
following statement.
P(μ
- 0.2σ <X 1 < μ + 0.2σ) <
P(μ - 0.2σ <X 2 <
μ + 0.2σ) ( 10 marks)
