ree size measures as diameter at breast height (DBH) Data for longleaf pine trees in two parts of a tract of land are compared. Suppose that you are planning a study in which you will measure the diameters of longleaf pine trees. Assume that the standard deviation for both parts is 20 cm. Suppose that a difference in mean DBH of 10 cm or more would be important to detect. You will use a t statistic and a two-sided alternative for the comparison. Find the power if you randomly sample 20 trees from each area to be compared for a significance level of 5%. Do not use the normal approximation. You will need to find the non-centrality parameter, then use the appropriate t distribution to calculate your answer.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
