All of them. I think. I'm not sure
Answer:
The correct option is B.
Step-by-step explanation:
It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.
He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.


The slope is -0.7, therefore option B is correct.
Nothing there.

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Answer:445$
Step-by-step explanation:
40hrs*9.75=390$
11*5=55$
390$+55$=445$
Answer:
Step-by-step explanation:
Let X be the monthly count of salmonellosis cases in South Dakota.
And X has Poisson(A 1.62)
E(X) = \lambda = 1.62
Var(X) = \lambda = 1.62
Standard Deviation (X) = \sqrt{\lambda} = \sqrt{1.62} = 1.27
c)
Mean of salmonellosis cases in South Dakota over a six month period is = 6*1.62 = 9.72
standard deviation of salmonellosis cases in South Dakota over a six month period is = 6*1.27 = 7.62
