Suppose that you have a set of data that has a mean of 34 and a standard deviation of 6. a) Is the point 28 above, below, or the same as the mean. How many standard deviations is 28 from the mean. b) Is the point 46 above, below, or the same as the mean. How many standard deviations is 46 from the mean. c) Is the point 43 above, below, or the same as the mean. How many standard deviations is 43 from the mean. d) Is the point 20 above, below, or the same as the mean. How many standard deviations is 20 from the mean.
If the population average height is 67" and you take a random sample of 25 people resulting in a sample average value of 66 with a standard deviation of 2. Determine the "t" score that you would use as a test score for this data, and solve it for "t".
1. Prove the following statements:a) The standard deviation is zero if all the observations have some constant value.b) The standard deviation does not change by the change of origin.c) The standard deviation is affected by the change of scale.
Jack's clothing sells on average, 25 shirts per week, sometimes a little more, sometimes a little less but typically a deviation of about 3. The cost per jacket is $65. Because Jack's is located in a sketchy part of town their insurance on inventory is 33% on all goods. The good news is free shipping to customers although UPS charges Jack's $8.50 for every delivery. It takes 2 weeks from the time jackets are ordered until they are received. Jack's supplier has said they only ship by pallet, and each pallet contains 75 jackets. If the reorder point is 50 what is the average flow time?
In a test, the average of the grades is 80 and the standard deviation is 5. John's grade is 70, so his grade is standard deviations the average. 2 below 10 --------- below 70 above equal to
6. A distribution with a µ = 55 and o = 6 is standardized so that the new mean and standard deviation will be u = 50 and o = 10. When the new distribution is standardized, what value will be obtained for a score of x = 52 from the original distribution? a. X= 45 b. X = 47 C. X= 52 d. X = 53

a) The average temperature (Centigrade) in London varies from 14C to 31C during the year. i. Calculate indices based on March, base = 100 ii. What is the %age variation between the highest and the lowest temperatures? Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Temp C 15 22 19 24 29 28 31 28 27 22 18 14 Index b) Below are the no of customers, visiting a local Tesco Express, in the first week of holiday season. The store manager would like to avoid stock out in the busy period. Provide forecast of sales on Saturday next week, using 3 point moving average and seasonal variation. Assume same seasonal variation next period.
There are two sets of numbers. Set A is 5, 5, 5, 5. & Set B is 4, 5, 6, 7. Without doing any calculations, what can you say about the standard deviations of the two sets of numbers? A. Sets A and B have about the same standard deviation. B. The only way to compare the standard deviations is to calculate them. C. Set A has a smaller standard deviation. D. Set B has a smaller standard deviation.
In one math class, the first exam had an average score of 81.2% with a standard deviation of 10.9%. The second exam had a mean score of 79.3%, with a standard deviation of 19.9%. Based on these numbers, tell whether each statement is true or false. 1. There were probably some students that took a zero on Exam 1. The statement is ▼(Choose one(True/False)). 2. Most students did better on the second exam. The statement is ▼(Choose one(True/False)).
