Answer:
CA = 32
Step-by-step explanation:
By intersecting chords theorem:
CA = 14 + ( 3 + 3x)
CA = 14 + ( 3 + 3*5)
CA = 14 + ( 3 + 15)
CA = 14 + 18
CA = 32

Answer:
Alpha (α) is used to measure the error for decisions concerning true null hypotheses, while beta (ß) is used to measure error for decisions concerning false null hypotheses.
Step-by-step explanation:
Suppose we have events X and Y.
1. If it is said that X equals Y, when X is actually not equal to Y, α is used in this case, the null hypotheses.
2. If X is said to not be equal to Y, when X is actually equal to Y, β is used in this case, the false null hypotheses.
Most likely not.
The reason behind this is that the random participants only include just under 10% of the population. This has the ability to oversee minority judgement.
Cluster sampling should be used. This splits the population up into groups. For instance, we could split it up by race and sample that way. Or split it up by net worth. Or occupation. Whatever works best for this survey!
Hope I helped!
