A web-based company has a goal of processing 95 percent of its orders on the same...

A web-based company has a goal of processing 95 percent of its orders on the same day they are received. If 485 out of the next 500 orders are processed on the same day, would this prove that they are exceeding their goal, using α = .025?

Steps:

1. Open Minitab on your computer.

2. There is no data file for this example. The information above contains summarized data (take info from story and plug into Minitab)

(a)	H₀:p ≤ .95 versus H_A: p > .95. Choose the right option.

a.	Reject H₀ if p-value < alpha
b.	Reject H₀ if p-value > alpha

Pick either A or B from above

a
b

(b)

Calculate the test statistic. (Round your answer to 2 decimal places.)

Test statistic

(c-1)	The null hypothesis should be rejected.

	True False

(c-2)	The true proportion is greater than .95.

	True No evidence to support

(c-3)	The company is exceeding its goal.

	True No evidence to support
