value is not affected by the sample size, therefore, it remains unchanged. Calculate the new Sp value, UCL, & LCL

Is it possible that a sample result could fall outside the control limits due to pure chance? It is statistically impossible possible that a sample result could fall outside of the control limits due to pure chance.

An insurance company has an online help service for its customers. Customer queries that take more than 6 minutes to resolve are categorized as 'unsatisfactory' experiences. To evaluate the quality of its service, the company takes 10 samples of 100 calls each while the process is under control. Click the icon to view the resulting p values a. Calculate the pand S, values and set up corto limits so that future sample a values should fall within the control Imits 99.7% of the time. The p value is 0.128.

Suppose the insurance company takes four additional samples, yielding the following p values: 0.88, 0.13.0.39 and 0.12.
