The standard deviation in the pressure required to open a certain wave is known to be ea15 psi Due to changes in the manufacturing process, the quity-control manager feels that the pressure variability has been reduced (a) Stade the null and abeative hypotheses in words (b) State the null and atemative hypotheses symbolically (e) Explain what it would mean to make Type (4) Explain what it would mean to make Type (4) State the nut hypothesis in words. Choose the correct an OA The standard deviation in the pressure required to open a certain valve is different from 15 pa OB The standard deviation in the pressure required to open a certain valve 1.5 p OC. The standard deviation in the pressure required to open any vate is 15 p OD. The standard deviation in the pressure regured to open a certain save is greater than 15 pe
