Related QuestionA sample of $n=36$ scores is selected from a normal distribution with a mean of $\mu=65 .$ If the sample mean is $M=59$, then compute the $z$ -score for the sample mean and determine whether the sample mean is a typical, representative value or an extreme value for each of the following: a. A population standard deviation of $\sigma=12$ b. A population standard deviation of $\sigma=30$ Remember that variance is standard deviation squared: variance = s2 and by the same equation, the standard deviation is the square root of variance: √variance = √s2 = s So in the first one, you were given the standard deviation, s=4. You want to find variance. Well, since variance =s2 v = (4)2 v = 16 That's the variance. For the second one, can I assume that s2 = 9? so in other words, the variance is 9. To find the standard dev, s, just take the square root: √s2 = s √9 = s 3 = s Math Lia H. A population of N = 100 scores has µ = 30 and σ = 4. What is the population variance?

Scores: 1, 3, 0, 4a. ss=10 and variance=2.5b.
What is the variance for the following population of scores scores 5 2 5 4?Summary: The variance for the following population of scores: 5, 2, 5, 4 is 1.5.
What is the value of SS for the following set of scores scores 0 1 4 5?Answer and Explanation: Scores are: 0,1,4 and 5. Hence the value of SS is 17 and none of the options is correct.
When the standard deviation is much less than 10 a score that is 10 points below the mean would be considered an extreme value true or false?Therefore, a standard deviation much less than 10 would make this point an outlier. The correct answer is D) When the standard deviation is much less than 10.
