The quality manager believes there may be a relationship between the experience level of an inspector and whether a product passes or fails inspection. Inspection records were reviewed for 630 units of a particular product, and the number of units which passed and failed inspection was determined based on three inspector experience levels. The results are shown in the following table. Decision Experience Level Low (< 2 years) Medium (2-8 years) High (> 8 years) Pass 150 285 101 Fail...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

A local bottler in Hawaii wishes to ensure that an average of 16 ounces of passion fruit juice is used to fill each bottle. In order to analyze the accuracy of the bottling process, he takes a random sample of 48 bottles. The mean weight of the passion fruit juice in the sample is 15.80 ounces. Assume that the population standard deviation is 0.8 ounce. (You may find it useful to reference the appropriate table: z table or t table)...
