Homework Help: statistics

Posted by EXHAUSTED ON MATH on Saturday, March 24, 2012 at 1:07pm.

The data was obtained from car crash experiments. The table values are the chest deceleration data (g) for the dummy in the driverís seat. Use a 0.05 significance level to test the null hypothesis that the different weight categories have the same mean. Do the data suggest that larger cars are safer?

Subcompact: 56,57,56,60,55
Compact: 46,51,54,48,51
Midsize: 51,53,48,45,45
Full-size: 45,48,40,44,51

Should null hypothesis be rejected? (circle)

YES/NO because the P-value is GREATER/LESS than the significance level

Do the data suggest that larger cars are safer? (circle)

YES/NO because the null hypothesis IS/IS NOT rejected.
