Given a table below which gives the years in A.D. for an archaeological excavation site using the method of tree ring dating:

Part A:
The sample mean is given by:

Therefore, the sample mean is 1268.
Part B:
We calculate the sample standard deviation as follows:

Part C:
The 90% confidence interval is given by:
Answer:
Form aray
Step-by-step explanation:
Neither form a line and it also have both parts and perpendicular
2(P+1)+3(P+2)>2
Distribute
2P+2+3P+6>2
Simplify
5P+8>2
Subtract 8 from both sides
5P>-6
Divide both sides by five
P>(-6/5)
Turn to mixed number and you're done.
P>-1 and 1/5
Try this option:
1 meter=1000 mm; 1 hour=60 min. From another side: 1 mm=0.001 m. and 1 min=1/60 h.
Using this rule:
620 mm/h=0.06*620 m/h=37.2 meters per hour.
answer: 0.06
Answer:
Step-by-step explanation:
10x +5=100
-5 -5
10x=95
10 = 10
X=9.5
So x is less than 10
