Diffusion and Solubility of Gases (B. Flaconn'eche, et al., Oil and Gas Science and Technology, 2001:262-278) reported on a stud

y of the effect of temperature and other factors on gas transport coefficients in semi crystalline polymers. The permeability coefficient (in 10-6 cm3 (STP)/cm. s. MPa) of CO2 was measured for extruded medium density polyethylene at both 60 degree C and 61 degree C. The results are as follows:
60⁰ C54516167576960606362
61⁰ C58606666686160

(1) Find Mean of 60 degree sample to nearest 0.1
(2) Find mean of 61 degree sample to nearest 0.1
(3) Find sample standard deviation of 60 degree sample to nearest 0.01
(4) Find Sample standard deviation of 61 degree sample to nearest 0.01
(5) What are the degrees of freedom?
(6) Center of Confidence interval? (7) Width of confidence interval (remember to multiply by 2?)
(8) If everything was the same except that we had one more sample in each group, would the above confidence interval get longer or shorter or stay the same?

Which graph represents the function over the interval [−3,3] ?<br><br> f(x)=⌈x+1⌉
CaHeK987 [17]

Answer: The correct graph is the bottom left graph.

Step-by-step explanation:

Given function is f(x)=ceil(x+1)

To plot graph of f(x) in interval of(-3,3) :

ceil(x+1) is ceiling function

The output of ceil(x) is least integer greater than x

for example ceil(5.5)=6

For an interval of (-3,-2):

Take x=(-2.4)

x+1=(-1.4)

y=f(x)=ceil(x+1)=(-1)

Similarly,

For an interval of (-2,-1):

Take x=(-1.4)

x+1=(-0.4)

y=f(x)=ceil(x+1)=(0)

For an interval of (-1,0)

y=f(x)=1

For an interval of (0,1)

y=f(x)=2

For an interval of (1,2)

y=f(x)=3

For an interval of (2,3)

y=f(x)=4

Thus, The correct graph is the bottom left graph.

In a population of 1000 snails, tests of snail color genes show that 160 snails are AA, 480 are Aa and 360 are aa. What is the f
Kipish [7]

Answer:

Option C.

Step-by-step explanation:

Total population = 1000 snails

AA = 160 snails

Aa = 480 snails

aa = 360 snails

Frequency of each type.

AA=\dfrac{160}{1000}=0.16

Aa=\dfrac{480}{1000}=0.48

aa=\dfrac{360}{1000}=0.36

Now, we get

A^2=0.16\Rightarrow A=\sqrt{0.16}=0.4

he frequency of the A allele in this population is 0.4.

Therefore, the correct option is C.
