Then, now that we have solved for T, we can evaluate and solve for t=20 minutes.
Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ;σ²)
= 6
X[bar]= 158.17
S= 19.87
The hypothesis is:
H₀: μₓ = μ
H₁: μₓ ≠ μ
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]) - (μₓ - μ)]/[Sa/√(1/nₓ + 1/)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
answer : the answer is - 1 using Y2 - y1 over X2 minus X1
Answer:
First one on The left
Step-by-step explanation:
Answer:
A point will only map onto itself if it is on the line. Therefore (I am assuming the first point is (4, -4)) the answer is (4, -4).
