Answer:
The ratio is 
Step-by-step explanation:
The question in English is
In a group of high school third graders, 38 are right-handed and 6 are left-handed. find the ratio of right-handed to left-handed
Let
x -----> number of students that are right-handed
y -----> number of students that are left-handed
we know that
To find out the ratio of right-handed to left-handed, divide the number of students that are right-handed by the number of students that are left-handed
so
we have
substitute
Simplify
Answer:
There is not enough evidence to support the claim that the bags are under filled.
Step-by-step explanation:
Given :
Population mean, μ = 433
Sample size, n = 26
xbar = 427
Variance, s² = 324 ; Standard deviation, s = √324 = 18
The hypothesis :
H0 : μ = 433
H0 : μ < 433
The test statistic :
(xbar - μ) ÷ (s/√(n))
(427 - 433) / (18 / √26)
-6 / 3.5300904
T = -1.70
The Pvalue :
df = 26-1 = 25 ; α = 0.05
Pvalue = 0.0508
Since Pvalue > α ; WE fail to reject the Null and conclude that there is not enough evidence to support the claim that the bags are underfilled
