Here, we're given the sample- 1,3,4,4
We're asked to find sample variance and sample s.d.-
To, obtain the sample variance, first we've to obtain the sample
mean:
where,
ith sample value, for all i=1(1)4
n: sample size
Now,
We're to obtain the Sample
Variance(s2 )-
Formula for Sample
Variance is given by-
Sample Variance is=2
As we know if we take the square root of the Sample variance
we'll get the Sample Standard Deviation(s).
Formula for Sample Standard Deviation is given
by-
Sample Standard Deviation=1.4

A population consists of 3 numbers: 2, 10 and 6. You randomly select a sample of 2 observations without replacement and calculate the sample mean. The variance of the sample mean is _____. Group of answer choices 4 8/3 4/6
Let the values of the random variable of interest in the population be given by the numbers {1, 2, 3}. Let p(x) = 1/3 for x = 1, 2, 3. Take samples of size 3 with replacement. Obtain the sampling distribution of the sample variance S^2 . Make sure to provide a table with all the samples you may obtain and their sample S^2 then summarize and give the distribution containing the unique values of S^2 and their probability.
Suppose nine items are sampled from a normally distributed population with a mean of 116 and a standard deviation of 17. The nine randomly sampled values are shown in the table. 145 111 114 141 117 143 100 71 102 Calculate the probability of getting a sample mean that is smaller than the mean for these nine sampled values. The probability that a sample mean is smaller than the mean for these nine values = (Round to four decimal places...
Suppose that we will randomly select a sample of 72 measurements from a population having a mean equal to 18 and a standard deviation equal to 9. (a) Describe the shape of the sampling distribution of the sample mean. Do we need to make any assumptions about the shape of the population? Why or why not? (b) Find the mean and the standard deviation of the sampling distribution of the sample mean. (Round your σx⎯⎯ answer to 1 decimal place.)...
