A population consists of the following four values: 12, 12, 14, and 16. a. List all samples of size 2, and compute the mean of each sample. Sample Values Sum Mean 1 2 3 4 6 b. Compute the mean of the distribution of the sample mean and the population mean. Compare the two values. Sample mean Population mean Both mean are

Three parts

The following refer to the following data set: 20 28 44 92 64 48 68 43 86 43 What is the mean (7) of this data set? mean = (Please show your answer to one decimal place.) What is the median of this data set? median = %3D What is the mode of this data set? mode = %3D

Determine if the data set is a population or a sample. The incomes of every employee at an amusement park.

Use R to determine whether the mean population by census tract in 2016 is higher than the mean population by census tract in 2012. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.  POP2012: 3166, 2210, 3784, 2472, 3157, 4046, 4536, 4084, 7612, 3536, 3187, 2696, 4003, 3889, 2319, 2559, 3051, 4871, 4052, 6767, 6243, 6637, 4066, 3212, 3586, 4835, 2679, 2893, 8868, 4989, 5407, 4703, 4111, 3549, 4974, 3153, 3972, 1920, 2039, 1493, 5510, 4730, 6220, 3478, 5012, 5026, 4350, 3788, 2601, 3492, 1515, 4231, 4344, 4094, 4075, 3210, 4576, 3663, 4388, 4402, 2969, 3418, 3583, 3793, 2284, 3251, 4026, 2714, 5506, 3730, 3913, 3853, 5914, 6073, 3569, 3022, 4801, 5119, 2710, 6259, 3859, 2912, 3611, 3437, 2149, 2414, 3858, 3888, 5878, 1678, 6040, 3779, 2225, 3248, 2039, 2459, 4316, 3712, 4916, 3331, 5079, 2047, 3249, 3579,…
