On a (very) large island, there are over 10,000 coconut trees. In 2019, you find that 5 of these trees produced the following number of coconuts:
2, 3, 4, 5, 6
Compute the standard deviation of coconuts produced in 2019 from this sample of trees. Round your answer to the 4th decimal place
Homework Answers
| Values ( X ) | Σ ( Xi- X̅ )2 | |
| 2 | 4 | |
| 3 | 1 | |
| 4 | 0 | |
| 5 | 1 | |
| 6 | 4 | |
| Total | 20 | 10 |
Mean X̅ = Σ Xi / n
X̅ = 20 / 5 = 4
Sample Standard deviation SX = √ ( (Xi - X̅
)2 / n - 1 )
SX = √ ( 10 / 5 -1 ) = 1.5811

The heights of pecan trees are normally distributed with a mean of 10 feet and a standard deviation of 2 feet. Show all work. Just the answer, without supporting work, will receive no credit. (a) What is the probability that a randomly selected pecan tree is between 9 and 12 feet tall? (Round the answer to 4 decimal places) (b) Find the 80th percentile of the pecan tree height distribution. (Round the answer to 2 decimal places) (a) For a...

Question Part Points Submissions Used 1.Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers...
