Question

In order to estimate the median amount of new credit card charges for the previous month, a financial service accountant randomly selects

credit card accounts and records the amount of new charges for each account for the previous month. The amounts are listed below. At

alpha

equals0.01

the accountant wants to know whether he can conclude that the median amount of new credit card charges for the previous month was more than

$ 300

Complete parts (a) through (e).

Start 2 By 5 Matrix 1st Row 1st Column $ 340.24 2nd Column $ 340.77 3rd Column $ 299.94 4st Column $ 207.67 5st Column $ 210.31 2nd Row 1st Column $ 293.35 2nd Column $ 285.68 3rd Column $ 214.18 4st Column $ 300.36 5st Column $ 200.31 EndMatrix

(a) Write the claim mathematically and identify

Upper H 0

and

Upper H Subscript a

The claim is

▼

median greater than $ 300

median less than or equals $ 300 median greater than or equals $ 300 median less than $ 300

What are

Upper H 0

and

Upper H Subscript a

Upper H 0

median greater than or equals $ 300

and

Upper H Subscript a

median less than $ 300

Upper H 0

median less than or equals $ 300

and

Upper H Subscript a

median greater than $ 300

Upper H 0

median less than $ 300

and

Upper H Subscript a

median greater than or equals $ 300

Upper H 0

median greater than $ 300

and

Upper H Subscript a

median less than or equals $ 300

(b) Determine the critical value.

The critical value is

nothing

(Type an integer or decimal rounded to the nearest hundredth as needed.)

The test statistic is

nothing

(Type an integer or decimal rounded to the nearest hundredth as needed.)

(d) Decide whether to reject or fail to reject the null hypothesis.

Reject

the null hypothesis.

Fail to reject

the null hypothesis.

(e) Interpret the decision in the context of the original claim.

At the

1 %

significance level,

▼

there is not

there is

enough evidence for the accountant to conclude that the median amount of new credit card charges for the previous month was more than

$ 300
