hi everyone i really really need help im soo behind on my stats work im relaly stuck on 2 assignments with a few questions left on both that i need to submit online can someone pls help me out.
1. a pareto diagram displays?
a. a random patter of defects
b. center line with lower and upper control limits
c. the causes of defects in order from most to least frequent
d. the cause of defects in order from least to most requent
2. the null hypothesis in a control procedure assumes that
a. the process is in control
b. the process is out of control
c. there is no variation in the process
d. there are no defectives being produced by the process
3. the x (x with the line over) is used to monitor the
a. variation of a process
b. level of a process
c. defective rate of process
d. cost of a process
4. a pchart is used to monitor the
a. variation of a process
b. level of a process
c. defective rate ofa process
d. cost of a process
5. a pchart involving samples of size 100 and a defective rate standart of po=.08 would result in the following lower and upper control limits:
a. LCL=.078 UCL=.082
b. LCL=.050 UCL=.110
c. LCL=.040 UCL=.120
d. LCL=.000 UCL=.161
6. an X(with the line over it) involving samples of size 16 and standars of mean =220 and o =96 would result in the follwing lower and upper control limits:
a. LCL=124 UCL=316
b. LCL=202 UCL-238
c. LCL=148 UCL=292
d. LCL=169 UCL=244
