The kyoto protocol was signed in 1997, and required countries to start reducing their carbon emissions. the protocol became enforceable in february 2005. in 2004, the mean co2 emission was 4.87 metric tons per capita. is there enough evidence to show that the mean co2 emission is lower in 2010 than in 2004? state the type i and type ii errors in this case, consequences of each error type for this situation from the perspective of the agency overseeing the protocol, and the appropriate alpha level to use. state why you picked this alpha level.

Step-by-step explanation: Type 1 error is the error of rejecting a true null hypothesis or giving a false positive conclusion while type 11 error is the non rejection of a false null hypothesis.

The type 1 error for this question is: The mean CO2 is lower in 2010 than in 2004. While the type 11 error is:The mean C02 is higher in 2010 than In 2004. The consequences of making a type 1 error is that it will lead to a misguided information, while the consequences of making a type 11 error is that it could lead to loss of lives . The appropriate alpha level to use is 0.01, the reason is because the level of confidence needs to be high when it comes to health issues.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

c. (3,2,6) is the answer.
