on the very far left it says (5,-1.5)
12 - 7 = 5
5/12
0.416
41%
You have a 41% chance of rolling a sum greater than seven.
Answer:
We don´t have at 95% of confidence, evidence to reject the publisher´s claim
Step-by-step explanation:
Population mean p₀ = 58 % or p₀ = 0,58
Hypothesis Test:
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p < p₀
For a significance level α = 0,05 means that CI = 95 % or CI = 0,95
z(c) = - 1,64
MOE = z(c)* √(p*q)/n
p - p₀ / √(p*q)/n = z(s)
And that z(s) is in the acceptance region
|z(s)| < |z(c)|
|z(s)| < 1,64
Then if that so we fail to reject H₀ . We don´t have evidence to reject the publisher´s claim

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.
