The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight-ounce s
Gekata [30.6K]

Answer:

The test results support the claim

Step-by-step explanation:

The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States was 423 eight ounce servings (Coca-Cola Company website, February 3, 2009).

Suppose you are curious whether the consumption of Coca-Cola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters.

A sample of 36 individuals from the Atlanta area showed a sample mean annual consumption of 460.4 eight ounce servings with a standard deviation of s = 101.9 ounces. Using α = .05, do the sample results support the conclusion that mean annual consumption of Coca-Cola beverage products is higher in Atlanta?

Hx: u <= 423 oz

Ha: u > 423 oz (claim)

z(460.4) = (460.4-423)/[101.9/sqrt(36)] = 2.2022

p-value = P(z > 2.2022) = 0.0138

Conclusion: Since the p-value is less than 5%

reject Hx at the 5% significance level.

The test results support the claim.

Find the solution of the initial value problem 2y−3y+y=0
tatuchka [14]
2y - 3y + y = 0

-y + y = 0

0 = 0

Hence, y has infinite possibilities of value since the equation is true without there being any use of y in it.

Hence, y could be any value.<span />

List two things that affect the end behavior of a polynomial function
Thepotemich [5.8K]

Step-by-step explanation:

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.
