1. A sample of n = 20 scores has a mean of M = 30.

a. If the sample standard deviation is s = 10, would a score of X = 38 be considered an extreme value (out in the tail of the distribution)?

X = 38 would not be considered an extreme value as it falls within one standard deviation above the mean

b. If the sample standard deviation is s = 2, would score of X = 38 be considered an extreme value (out in the tail of the distribution)?

X = 38 would not be considered an extreme value as it falls within 4 standard deviations above the mean

I know this question is answered here on textbook solutions for Essentials of Statistics for Behavioral Sciences: 6th Edition (Chapter 4 Problem 10)

But I simply do not comprehend this concept and I would like to.

Thank you !

Suppose you have a sample size of n = 20, with a sample mean of 65 and a sample standard deviation of 15. Suppose the population mean is thought to be 50. You want to find out whether your sample mean is different from the population mean. Which test should you use? Select one: a. paired t-test b. two proportion z-test c. one proportion z-test d. two sample t-test e. one sample t-test.

(1.) A normal population has a mean of µ = 100. A sample of n = 36 is selected from the population, and a treatment is administered to the sample. After treatment, the sample mean is computed to be M = 106. Assuming that the population standard deviation is σ = 12, use the data to test whether or not the treatment has a significant effect. Use a one tailed test. Hypothesis: Zcrit= z test calculation: Conclusion: (2.) A mood questionnaire...
