The standard deviation in the pressure required to open a certain valve is known to be e=0.7 psi. Due to changes in the manufacturing process, the quality control manager feels that the pressure variability has increased. (a) Determine the null and attemative hypotheses. (b) Explain what it would mean to make a type or (c) Explain what it would mean to make a Type llenor (a) State the hypotheses 179 H₂ (Type integers or decimals. Do not round) (b) Which of the following is a Type 1 error? OA The manager fails to reject the hypothesis that the pressure variability is 0.7, when it is the true pressure variability OB. The manager rejects the hypothesis that the pressure variability is 0.7, when it is the true pressure variability OC. The manager fails to reject the hypothesis that the pressure variability is 0.7, when the true pressure variability is greater than 0.7 OD. The manager rejects the hypothesis that the pressure variability is 0.7, when the true pressure vanability is greater than 0.7. (e) Which of the following is a Type 1 error? OA The manager rejects the hypothesis that the pressure variability is 0.7, when it is the true pressure variability OB The manager rejects the hypothesis that the pressure variability is 0.7, when the true pressure variability is greater than 0.7 OC. The manager fails to reject the hypothesis that the pressure variability is 0.7, when it is the true pressure variability OD. The manager fails to reject the hypothesis that the pressure variability is 0.7, when the tue pressure variability is greater than 0.7
