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.

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

Answer from: Quest

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = $\frac{-8+3}{4-7}$ = - $\frac{5}{3}$

y = - $\frac{5}{3}$ x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - $\frac{20}{3}$ + c ⇒ c = - $\frac{4}{3}$

y = - $\frac{5}{3}$ x - $\frac{4}{3}$ ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
