suppose that a company claims that its coffee cans contain 9.4 ounces of
coffee, on average. you take many large samples, and find, each time, that the
mean weight of the sample is within the 95% confidence interval. which of
the following would be a reasonable conclusion?
o
a. the company's coffee cans contain less than 9,4 ounces of
coffee, on average.
o
b. the company's coffee cans do not contain 9.4 ounces of coffee,
on average.
o
c. the company's coffee cans contain 9.4 ounces of coffee, on
average
o
d. the company's coffee cans contain more than 9.4 ounces of
coffee, on average

do you have the measurements?

your answer is the frist one

hop i

where is the diagram? shown below where? ?

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
