Answer:

6.4 = k*4

k = 6.4 / 4

k = 1.60

11.2 = k * 7

k = 11.2 / 7

k = 1.60

16 = k * 10

k = 16/10

k = 1.60

20.8 = k * 13

k = 20.8/13

k = 1.60

Relative density was determined for one sample of second-growth Douglas fir 2 x 3 4s with a low percentage of juvenile wood and

Citrus2011 [14]

Answer:

0.03865

Step-by-step explanation:

Since the true density for the two types of trees are given, we would evaluate the average for both of them

Low percentage of juvenile wood density = 0.523 and 0.0543

Average density = 0.523 + 0.0543/2

Average density = 0.55015

Moderate percentage of juvenile wood density = 0.489 and 0.0450

Average density = 0.489 + 0.0450/2

Average density = 0.5115

Therefore, difference in true average density for the two woods are = 0.55015 - 0.51150

= 0.03865
