-12
Step-by-step explanation:
There are 5 trumpet players.
if there are 15 saxophone players, there are 10 less trumpet players making it 5.
Answer:
a) No
b) No
c) P value is more than 0.05.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 12 ounces
Sample size, n = 49
P-value = 0.136
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
a) Alpha, α = 0.05
Since, p-value > α,
The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag.
b) Alpha, α = 0.10
Since, p-value > α,
The null hypothesis should not be rejected. We accept the null hypothesis and reject the alternate hypothesis. We conclude that the average chip weight is 12 ounces per bag.
c) The evidence is statistically significant at the .05 level means that the p value is more than 0.05.
Answer:
The x intercept is (-2,0) and the y intercept is (0,-5/2)
Step-by-step explanation:
− 5 x − 4 y = 10
To find the y intercept, set x =0 and solve for y
-5(0) -4y =10
-4y =10
Divide each side by -4
-4y/-4 = 10/-4
y = -5/2
The y intercept is (0,-5/2)
To find the x intercept, set y =0 and solve for x
-5x -4(0) =10
-5x=10
Divide each side by -5
-5x/-5 = 10/-5
x=-2
(-2,0)
