Sample Means if you select a sample of a certain size. μX= μ. μ = i=1NXiN (formula for mean) . σ = i=1N(Xi-μ)2N Although you do not know how close the sample mean of any particular sample selected comes to the pop mean, you know that the mean of all possible sample means that could have been selected = the pop mean. Standard

smallest dealer had 11 cars sold and the largest had 154 cars sold. If you were going to create a frequency distribution of the number of cars sold using six classes in your frequency distribution, which of the following might be a reasonable first class? (a) 0 to 25 _ (2) Give that a sample of 25 had x = 75, and (x-x)² = 48 the mean and standard deviation are _

marsh and put on a plant press. The location of each distinct plant species was documented. The purpose of doing this experiment the second week was to firstly, collect the pitfall samples, and secondly, avail the larger sample size after the second week. The larger sample size ensured that the results of the experiment were more significant, since sampling for two weeks is better than sampling for one week. Each group had a total of 12 vials from the first week and 14 vials from the second week.
