Suppose samples of 2 are drawn from this population. This situation is an example ol'the sampling distribution ofthe sample mean for a normal population widi population variance is A. unknown C. large B. known D. small Suppose that the rice mill wants to test its product to find out whether it meets the average weight ofce of 50 kilograms with a standard deviation Df0.18 kg. Thirty sacks of rice are weighed and found to have an average weight of 50.8 kg and a standard deviation of l15kg. The rice mill owner is in a situation ofrhe sampling distribution of the sample mean with population vssnce is , A. unknown C. large B. known D. small The average family income in the Philippines in 2019 was P22,250 with a standard deviation of P1,250. In a certain municipality, a sample of 50 families had an average income of \"5.000. This situation is about the sampling distribution of the sample mean where the population . A. Variance is know B. Variance is unknown C. Standard deviation is small D. Standard deviation is large This is used to determine the probability of an event by transforming the mean of the sample to a variable of this distribution where the population variance is unknown and the sample size is less than 30.
