Hi everyone,
I would like an estimate that the probability of the machine will work without failing between a certain time.
The machine should run 7.67 everyday. But the machine breaks down time to time. I would like to know if I schedule a Product to run say at 3.17 hours on that machine or if I schedule a product to run 7.67 hours what are the percentages of the machine will work without failing in the 3.17 hours or at 7.67 hours?
I know in excel there is a function call WEIBULL to help modeling machine lifetimes but I do not know where to start.
Here is my data below.
Column-A
Machine Name
Cast machine-1
Cast machine-1

Column B is the data for the last 2 weeks of the number of hours it ran until hitting downtime.
Column-B
Life of the Machine
7.01
4.16
7.67
5
2.12
1.2
6.01
7.2
3.01
1.99
7.20
