Answer:
Area is increasing
Step-by-step explanation:
Let x be the length of rectangle and y be the width of rectangle
We are given that
x=3 in
dx/dt=1 in/min
y=2 in
dy/dt=-0.5/min
We know that
Area of rectangle,
Differentiate w.r.t t
Substitute the values
Hence, the area of rectangle is increasing.
Answer:
C. Type I error
Step-by-step explanation:
Hello!
The hypothesis tested was:
H₀: μ = 7
H₁: μ > 7
The decision was taken: Reject the null hypothesis.
Reminder:
There are four decisions you can take when you make a hypothesis test.
1. Reject the null hypothesis when the hypothesis is false (This is a correct decision)
2. Reject the null hypothesis when the hypothesis is true (This decision is also known as Type I error)
3. Fail to reject the null hypothesis when the hypothesis is true (This is a correct decision)
4. Fail to reject the null hypothesis when the hypothesis is false (This decision is also known as Type II error)
Since they concluded, that the average process time vas greater than 7 days, when it was 7 days, they rejected the null hypothesis when it was true. This is a Type I error and its associated probability is α.
I hope it helps!
