Listed below are the lead concentrations in μ​g/g measured in different traditional medicines. Use a 0.05 significance level to test the claim that the mean lead concentration for all such medicines is less than 14 μ​g/g. Assume that the sample is a simple random sample. 18 11.5 5.5 8.5 5.5 14 11 6 10.5 15.5
Assuming all conditions for conducting a hypothesis test are​ met, what are the null and alternative​ hypotheses?
A.
H0​: μ=14 μ​g/g
H1​: μ>14 μ​g/g
B.
H0​: μ=14 μ​g/g
H1​: μ<14 μ​g/g
Your answer is correct. C.
H0​: μ>14 μ​g/g
H1​: μ<14 μ​g/g
D.
H0​: μ=14 μ​g/g
H1​: μ≠14 μ​g/g
Determine the test statistic.
nothing ​(Round to two decimal places as​ needed.)
Determine the P-value?

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
