Answer: The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample = 31.2 pounds .
Step-by-step explanation:
The weights of spawning Chinook salmon in the Columbia river are normally distributed.
Given : The mean weight from your sample is 31.2 pounds with a standard deviation of 4.4 pounds.
The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample i.e. is 31.2 pounds because the best point estimate for population mean is the sample mean. [in normal distribution]

Step-by-step explanation:
Answer:
A) AB = 24 and DE = 12
Step-by-step explanation:
Since the side CA is the double of side DF and the side CB is double the side FE, to get SIMILAR triangles, we also need the third sides to in the same proportion... so AB = 24 and DE = 12
So the first triangle would have measurements:
CA = 12
CB = 20
AB = 24
The second triangle would be scaled by 2:
DF = 6
FE = 10
DE = 12
