Question

2. Look at the phStat output for hypothesis testing for the proportion, using the p value approach, determine the appropriate conclusion. Should you accept or reject the null hypothesis? Why? Z Test of Hypothesis for the Proportion Data Null Hypothesis ? = 0.2500 Level of Significance 0.05 Number of Items of Interest 73 Sample Size 240 Intermediate Calculations Sample Proportion 0.304166667 Standard Error 0.0280 Z Test Statistic 1.9379 Upper-Tail Test Upper Critical Value 1.6449 p-Value 0.0263 3. Type II error is known as the consumer's risk because, when it occurs in quality control settings, the customer is getting a product from a process that is not performing properly. Is this a true or false statement? Explain.
