Complete question:

A student in an introductory statistics course investigated if there is evidence that the proportion of

milk chocolate M&M's that are green differs from the proportion of dark chocolate M&M's that are

green. She purchased a bag of each variety and her data are summarized in the following table:

Milk chocolate- Green:8 Not Green: 33 Total: 41

Dark Chocolate- Green: 4 Not green: 38 Total :42

a) Define the appropriate parameter(s) for this data.nd state the hypotheses for testing if the proportion of green M&M's differs for milk chocolate and dark chocolate M&M's.

b. The p-value is 0.32. Use this p-value to make a decision about these hypotheses with an alpha of 0.05. Be sure to word your decision in the context of the problem. Include an assessment of the strength of your evidence.

Step-by-step explanation:

a. P_{mc} = Proportion of milk chocolate M&M 's that are green

P_{dc} = Proportion of dark chocolate M&M 's that are green

H_{0} : P_{mc} = P_{dc}

H_{0} : P_{mc} ≠  P_{dc}

b. This p-value provides no evidence that the proportion of green candies differs for milk chocolate and dark chocolate M&M's

This question is incomplete

Complete Question

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

The entire little league division that The Hawks belong to has the same ratio of redheads to everyone else.

What is the total number of redheads in that division if the total number of players is 126?

Answer:

18 red heads

Step-by-step explanation:

We are told:

The little league team called the Hawks has 7 brunettes, 5 blonds, and 2 red heads.

Hence, we have the ratio

7: 5: 2

Adding up the ratios together

7 + 5 + 2

= 14

The total number of players is 126

Hence, the total number of redheads in that division is

2/14 × 126

= 18 red heads.

. This relation is an inverse variation.
IrinaK [193]

Answer:

The equation that represents the relation is;

d. y = -16/x

Step-by-step explanation:

The

An inverse variation of an ordered pairs is the set of ordered pairs that is given by the relationship that as one variable in an ordered pair increases, the other decreases and vice versa

Mathematically, an inverse relation can be expressed as follows;

y ∝ 1/x

From which we have;

y = k/x, where, "k", represents the constant of proportionality

Therefore, we have;

k = y × x

The given ordered pair are;

{(-1, 16), (2, -8), (4, -4)}

Therefore, k = y × x = 16 × (-1) = -8 × 2 = -4 × 4 = -16

The given function is y = k/x = -16/x

Therefore, y = -16/x.
