Permutations of 9 flower pots taken 4 at a time:
nPr = 9P4 = 3,024 - displays possible when order of flower pots matters.
I hope this helps
I at least think what this is asking.
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!
You first graph both equations.
Once that is done find the point of intersection (where the equations cross).
The point where they meet up (intersect) will be your solution.

the decimals are commas and the double decimal is a real decimal
