A fаctоry hаs been аble tо prоduce a very specialized nano-technology component with 80% reliability, that is, 80% of the components passed its quality assurance requirements. They have now changed their manufacturing process and hope that this has improved the reliability. To test this, they took a random sample of 159 components produced using the new process and found that 141 components passed the quality assurance test. Does this show a significant improvement over the old process? Use a significance level of 5%. Answer the following questions, 1) Select the alternative hypothesis 2) Calculate the test statistic 3) Calculate the p-value
