WebMay 5, 2024 · Solution: Given: μ = 70 kg, σ = 15 kg, n = 50. As per the Central Limit Theorem, the sample mean is equal to the population mean. Hence, = μ = 70 kg. Now, = 15/√50. ⇒ ≈ 2.1 kg. Problem 2. A distribution has a mean of 69 and a standard deviation of 420. Find the mean and standard deviation if a sample of 80 is drawn from the distribution. WebMar 24, 2024 · Central Limit Theorem. Let be a set of independent random variates and each have an arbitrary probability distribution with mean and a finite variance . Then the normal form variate. (1) has a limiting cumulative distribution function which approaches a normal distribution . Under additional conditions on the distribution of the addend, the ... WebThe Central Limit Theorem defines that the mean of all the given samples of a population is the same as the mean of the population(approx) if the sample size is sufficiently large enough with a finite variation.
