The length of time taken on the SAT for a group of students is normally distributed with a mean of 2 hours and a standard deviation of 0 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean ... WebProperties of the x ̄ sampling distribution: μx ̄ = μ and σx ̄ = σ/n where μ and σ are the population mean and standard deviation, respectively. In addition, when the population distribution is normal or the sample size is large, the sampling distribution of x ̄ is (approximately) normal. historia bayernu monachium
