1. A company has two product samples A and B in each product line, each sample has a mean and standard deviation as indicated in the following table. Sample A | Sample B --- | --- Mena = 12 | Mean = 6 Standard deviation = 3 | Standard deviation = 2 a. Which of the samples, A or B, is statistically reliable? (2 marks) b. Which of the two will you recommend to the management? Explain why. (8 marks)

Step 1
To determine which sample is statistically more reliable, we need to look at the standard deviation. The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation means that the values tend to be close to Show more…

1) After 3 points have been added to every score in a sample, the mean is found to be M= 83 and the standard deviation is s = 8. What were the values for the mean and the standard deviation for the original sample? 2) A population has a mean of μ= 30 and a standard deviation of σ = 5. If 5 points were added to every score in the population, what would be the new values for the mean and the standard deviation? 3) After every score in a sample has been multiplied by 4, the mean is found to be M = 48 and the standard deviation iss= 12. What were the values for the mean and the standard deviation for the original sample?
