QUESTION 26 The Central Limit 11180er states that ' The sampling distribution of any statistic will be approximately normally distributed as long as you take a large enough sample. ' None of the given statements is correct. The sampling distribution of any statistic will be approximately normally distributed as long as the original population is normal. ' The distribution ot the sample will be approximately normally distributed as long as the sample size is large enough. QUESTION 2? The time spent on social media platforms per day by adults follows a normal distribution with a mean of 120 minutes and a standard deviation of 36 minutes. If 64 adults are randomly selected. then the distribution of the sample mean time spent on social media platforms is Approximately normal with mean 120 minutes and standard deviation 4.5 minutes. ' Exactly normal with mean 120 minutes and standard deviation 4.5 minutes. ' Can't be determined without more information Exactly normal with mean 120 minutes and standard deviation 64 minutes.
