A traffic safety company publishes reports about motorcycle fatalities and helmet use. In the first accompanying data table, the distribution shows the proportion of fatalities by location of injury for motorcycle accidents. The second data table shows the location of injury and fatalities for 2070 riders not wearing a helmet.

Proportion of fatalities by location of injury for motorcycle accidents

Location of injury	Multiple locations	Head	Neck	Thorax	Abdomen/ Lumbar/ Spine	Full data set
Proportion	0.570	0.310	0.030	0.060	0.030

Location of injury and fatalities for 2044 riders not wearing a helmet

Location of injury	Multiple locations	Head	Neck	Thorax	Abdomen/ Lumbar/ Spine
Number	1024	850	34	87	49

Compute the expected counts for each fatal injury.

Location of injury	Observed Count	Expected Count
Multiple Locations	1024	?
Head	850	?
Neck	34	?
Thorax	87	?
Abdomen/Lumbar/Spine	49	?

(Round to two decimal places as needed.)

What is the P-value of the test?

P-value=_____?

(Round to three decimal places as needed.)
