1) A manufacturing facility produces 1280 x 1024 LED (light-emitting diode) displays. The facility would like to determine if the median number of bad pixels per billion in a shipment of LED displays is greater than 350. a) What is the appropriate null and alternate hypothesis to determine if the median number of bad pixels per billion in a shipment of LED displays is greater than 350? b) Choose a level of a. Use a = 0.05 for this problem. c) To test the hypothesis, the manufacturing facility random selects 24 shipments of LED displays and determines the number of bad pixels per billion. The data appear in the LED Displays worksheet of the Chp 18 data workbook on Moodle. Calculate sample statistic, i.e., the number of plus signs. Sketch the sampling distribution. Include the critical value and test statistic. d) e) Draw a conclusion for the hypothesis test. Make sure you state your conclusion in the context of the problem. f) Calculate the p-value
