Q
Looking for some guidance from our statistical analysis experts...
My situation is my company has been monitoring the % of poles that we have had to straighten and we have had an increase lately. 30-40 ft length steel poles are dipped in a hot metal bath to be galvanized at one of our suppliers. I had a suspicion that things were getting worse when the weather turns colder, but was told that poles are allowed to reach ambient indoors and outside temperature is negligible. Regardless of the cause, looking at the %'s below or attached, statistically can I say that something in the process has changed?
