PART 1 AND 2 OF THIS MULTIPART QUESTION ARE BOTH ALREADY COMPLETE, PLEASE LOOK AT THE BOTTOM OF PIC, I NEED HELP WITH CALCULATING THE P-VALUE:

Polyester resins reinforced with fiberglass are used to fabricate wall panels of restaurants . It is theorized that adding cement kiln dust ( CKD ) to the polyester composite will increase wall panel hardness . In a study , hardness ( joules [ V ] per squared centimeters ) was determined for three polyester composite mixtures that used a 40% CKD weight ratio . The hardness values were reported as 83 , 84 , and 78 J / cm = . Research has shown that the mean hardness value of polyester composite mixtures that use a 20% CKD weight ratio is u = 76 J / cm = . In your opinion , does using a 40 % CKD weight ratio increase the mean hardness value of polyester composite mixtures ? Support your answers statistically .* OA . Ho : H * 76 O B . HO : H = 76 Ha : H = 76 Ha : H * 76 `/ C . Ho : H = 76 OD . HO : H = 76 Ha : H > 76 Ha : H
