If you can't help with all parts pls skip I'll rate accordingly positive

The first 5 rows of the table used to calculate the standard deviation of 25 observations appears below. xbar = x¯ and (x-xbar)^2 = (x−x¯)2

x (x-xbar) (x-xbar)^2

[1,] 62 -90 NA

[2,] 260 108 11664

[3,] 139 -13 169

[4,] 338 186 34596

[5,] 103 -49 2401

Use the table from the question above to answer the following questions. All answers are integers, do not include a decimal point.

a) The mean is _______ .

b) The missing value in row 1 is ______ .

c) The sum of the values in column x is ______ . (Hint use the value of the mean and the fact that there are 25 observations).

d) The sum of the values in column (x-xbar) is ____ .

e) The variance is 7164.083. Use this to find the sum of the values in column (x-xbar)^2. _______.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
