A new process for producing a type of resin is supposed to have a mean cycle time of 3.5 hours per batch. Six batches are produced, and their cycle times, in hours, were: 3.45, 3.47, 3.57, 3.52, 3.40, and 3.63. You decided to conduct a hypothesis test to determine whether the mean cycle time is greater than 3.5 hours.

a. Use the critical value approach.
b. Use the p-value approach

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

answer: 20

step-by-step explanation:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
