A botanist collected one leaf at random from each of 10 randomly selected mature maple trees of the same species. The mean and t
Zarrin [17]

Answer:

One sample t-test for population mean would be the most appropriate method.

Step-by-step explanation:

Following is the data which botanist collected and can use:

  • Sample mean
  • Sample Standard Deviation
  • Sample size (Which is 10)
  • Distribution is normal

We have to find the best approach to construct the confidence interval for one-sample population mean. Two tests are used for constructing the confidence interval for one-sample population mean. These are:

  • One-sample z test for population mean
  • One-sample t test for population mean

One sample z test is used when the distribution is normal and the population standard deviation is known to us. One sample t test is used when the distribution is normal, population standard deviation is unknown and sample standard deviation is known.

Considering the data botanist collected, One-sample t test would be the most appropriate method as we have all the required data for this test. Using any other test will result in flawed intervals and hence flawed conclusions.

Therefore, One-sample t-test for population mean would be the most appropriate method.

80,40,20,10,__what the missing number
Scrat [10]

Answer:

5

Step-by-step explanation:

The sequence is a "/2 sequence", which means each number equals half of the previous one.

40 is half of 80.

20 is half of 40.

10 is half of 20.

5 is half of 10.

Hope it helped,

Which data set does the histogram represent?
MAVERICK [17]

Answer/Step-by-step explanation:

Ok so there is

3, 0-4                  4, 5-9                2, 10-14             1, 15-19       1, 20-24

so you can get rid of the last one saying it has more than 1 number between 20-24.

The 3rd one has to short of numbers for 0-4.

the second one has way to many 0-4's when there should be 3 of them.

therefore your answer is The firstone.
