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. 
= Proportion of milk chocolate M&M 's that are green
= Proportion of dark chocolate M&M 's that are green
≠
b. This p-value provides no evidence that the proportion of green candies differs for milk chocolate and dark chocolate M&M's
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
Answer:
x = 18 (Smaller number)
y = 35 (Larger number)
Step-by-step explanation:
To solve, begin by setting up a system of equations.
'x' being the smaller number, while
'y' is the larger number.
We can construct the equations:
x + y = 53
3x = y + 19
Rearrange the second equation to equal 'y':
3x - 19 = y
Plug this value of 'y' into the first equation:
x + 3x - 19 = 53
Combine like terms and simplify:
4x - 19 = 53
4x = 72
x = 18
Plug in this value for 'x' into an equation to solve for 'y':
18 + y = 53
y = 35.
