Please help me with this problem.

Two types of plastic is suitable for the use by an electronic component manufacturer, The braking strengthof the plastic is important.

It is known tht sigma1=sigma2=7 kN/m^2.

From a random sampleof size n1=10. N2=12. Xbar1=1120 Xbar2= 1070.

The company will not adopt plastic 1 unless its mean breaking strenth exceeds that of plastic 2 by at least 10 kN/M^2

Q1:Based on the sample indormation, should it use plastic 1, alphy=0.05.

Q2:Find the P value?

Please help

Thank you.
