Question

Create a Control Limit chart for the following: You are a manager at RadioTag Inc., a maker of RFID tags for US military and private use (e.g., Wal Mart). Your process assembles radio id tags to certain specifications – 95.5 confidence intervals, however as they come off the assembly line a test is run on each tag to determine whether the frequency works or does not (hint the data are dichotomous distributed binary). Below are the data you collected over a 2-week period:                                                                                                                                                                                                                                                                                                                                                                GRAPH GOES UNDER THIS

1.         P bar =

SD of P bar =

UCLP Bar =

LCLP bar =

B) Graph and Plot the data. Round answers to three places.

Clearly identify the P bar, s.d. of Pbar, UCL, LCL (make sure the graph elements are labeled) and identified in A above.

C) Compare p value to a. What is the result?
