Question

The weights (in pounds) of

vehicles and the variability of their braking distances (in feet) when stopping on a dry surface are shown in the table. Can you conclude that there is a significant linear correlation between vehicle weight and variability in braking distance on a dry surface? Use

α=0.01.

Weight, x	5930	5390	6500	5100	5890	4800
Variability in braking distance, y	1.76	1.95	1.91	1.62	1.64	1.50

1.Setup the hypothesis for the test.

Choose a or b

H0:

▼

A.less than or equals≤

b.less than<

c.equals=

d.greater than>

e.greater than or equals≥

f.not equals≠

Ha:

▼

A. less than or equals≤

b.less than<

c.equals=

d.greater than>

e.greater than or equals≥

f.not equals≠

2.Identify the critical value(s). Select the correct choice below and fill in any answer boxes within your choice.

(Round to three decimal places as needed.)

Fill the correct answer

The critical value is=

The critical values are −t₀= and t₀=.

Calculate the test statistic.

(Round to three decimal places as needed.)

3.What is your conclusion?

Choose A or B?

There

▼

(A)is not

(B)is

enough evidence at the

level of significance to conclude that there

▼

(A)is not

(B)is

a significant linear correlation between vehicle weight and variability in braking distance on a dry surface.
