Answer:
3.113, 4.507
Step-by-step explanation:
From the given values:
Mean = 3.81
Standard deviation = 1.74
Therefore
M = √(1.72/18) = 0.4
μ = M ± t(sM)
μ = 3.81 ± 1.74*0.4
μ = 3.81 ± 0.697
Recall that the mean is estimated at 90% confidence level,
Hence,
= 90% CI [3.113, 4.507]
Answer: 1/3
Step-by-step explanation: slope is the difference between the y values over the difference of the x values
Answer:
Infinitely many solutions
Step-by-step explanation:
Solve y = 3x+1 for y
y = 3x+1
Substitute 3x+1 for y in -6x+2y = 2
−6x+2y = 2
−6x+2(3x+1) = 2
2=2
2+−2=2+−2
0=0
Simple, y can be anything. Because you have no other variable on the other side to use; y can be whatever you want to plug-in to the equation.
