Answer:
4%
Step-by-step explanation:
The formula for percent of increase is increase divided by original number x 100
So here, our increase was 1 and our original number was 25, so 1/25 equals .04 and .04 x 100 = 4
Answer:
The difference is significative we reject H₀
Step-by-step explanation:
Normal Distribution
Population mean X₁ = 150
Population standard deviation σ = 25
Sample size n = 125
Sample mean X₂ = 158
1.-CI = 95 % significance level α = 5% α = 0,05
From z-table α = 0,05 z(c) = 1,64 ( the test is one-tail test to the right)
2.-Hypothesis Test
Null Hypothesis H₀ X₂ = X₁
Alternative Hypothesis Hₐ X₂ > X₁
3.-To compute z(s)
z(s) = ( X₂ - X₁ ) / σ/√n
z(s) = 8 * 11,14 /25
z(s) = 89,12/25
z(s) = 3,56
4.- Comparing z(s) and z(c)
z(s) > z(c)
Then z(s) is in the rejection region we reject H₀
Slope:1
y-intercept: -4
sorry i don know how to show you a graph on here
Answer:
1/2
Step-by-step explanation:
6/12 =
(2 × 3)/(22 × 3) =
((2 × 3) ÷ (2 × 3)) / ((22 × 3) ÷ (2 × 3)) =
1/2
