Answer:
32 days must be sampled to test the proposed hypothesis.
Step-by-step explanation:
Consider the provided information.
The average number of person-hours per day spent on these task was 
.
The actual value of μ is 12 hours or less i.e μ=12
She wants a test having α=0.05
The probability of a type II error of at most β=0.10 and σ=7.64.
δ = μ-μ0
= 12-16
= -4
Now use the formula for calculating the sample size:
Substitute the respective values.
Hence, 32 days must be sampled to test the proposed hypothesis.
You would move 3 spaces to the left then 3 down
Step-by-step explanation:
step 1. so you want to graph 2 linear equations?
step 2. y = (-1/3)x + 6. put a dot on the y intercept (0, 6).
step 3. draw the line through (0, 6) with a slope of -1/3 (down 1 and to the right 3).
step 4. y = 3x + 6. put a dot on the y intercept (0, 6).
step 5. draw the line through (0, 6) with a slope of 3/1 (up 3 and to the right 1).
Answer:
The SQ Root of 493
Step-by-step explanation:
Becaues this triangle is a right triangle, we can find the missing side usiing the pythagorean theorum.
The pythagorean theorun states A^2 + B^2 = C^2, so 18^2 + 13^2= 439
Then all you have to do is find the sq root of 439, but this question askes you not to.
Hope this helps :)
The answer is SA=294
To get it you do 6*7^2
