. Random samples of size n = 3 are drawn from the population which consists of the values 4 5 9 IO 12 Construct a sampling distribution of the sample means. . Refer to Problem 3. Find the mean or expected value of the sample means by following the process in Reading 2 Example 2. . Refer to Problem 3, find the standard deviaon of the sample means. . Consider a population of 6 vehicles. The speed of the vehicles on a particular stretch of roadway are given below. Construct a sampling distribution of the sample means for samples of size n = 3. 64 kph 72 kph 84 kph 50 kph 60 kph 96 kph . Refer to Problem 6. find the mean and standard deviaon of the sample means. . Retem'ng to Problem 6. the speed of the vehicles on a particular stretch of roadway are given. Construct a sampling distribution of the sample means for samples of size n = 2. 64 kph 72 kph 84 kph 50 kph 60 kph 96 kph
