a.Using the Jarque-Bera test, select the competing hypotheses in order to determine whether or not MPG follow the normal distribution.

H₀:S= 0 andK= 0;H_A:S 0 orK 0H₀:S= 0 andK= 0;H_A:S< 0 orK< 0H₀:S= 0 andK= 0;H_A:S> 0 orK> 0

b-1.Calculate the value of the Jarque-Bera test statistic.(Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)

Test statistic

b-2.Approximate thep-value.

p-value < 0.010.01 p-value < 0.0250.025 p-value < 0.050.05 p-value < 0.10p-value 0.10

c.At= 0.05can you conclude that MPG are not normally distributed?

Yes since thep-value is less than.Yes since thep-value is more than.No since thep-value is less than.No since thep-value is more than.
