In an existing process, we have found that the lower and upper control limits for X-bar chart are 8.09 and 8.59respectively. Whereas, the lower and upper control limits for R-chart are 0 to 1.25 respectively. The followingmeasurements for one sample are taken: 8.5, 9.14, 8.28, and 9.2. Using both the X-bar chart and R-chart for thisparticular sample, what we can conclude about the overall processa.Insufficient information to concludeOb. Process is in-controlO c.Perfect processO d.

Customers at IT Phone Call Center have been complaining that they are waiting too long for service. The managers at the call center have taken notice and asked you to do some investigating to determine the typical service time for their customers for morning shifts compared to evening shifts. You collect the following samples (time in minutes): Morning shifts: 8, 15, 16, 18, 18, 20, 21, 21, 21, 56 Evening shifts: 3, 11, 12, 14, 22, 22, 30, 33, 34, 47 Explain in detail which descriptive statistic (mean, median, or mode) you would utilize to communicate the typical service time to your boss for each shift and why. In your explanation, be sure to include which shift (morning or evening) has the quicker turn-around time.
In 1991, a person was working as an engineer at a paper company when they were laid off in round 2 of several rounds of layoffs by the company. This person sued the company for age discrimination. The engineer claimed that the laid off workers were older than others. The age of randomly selected 10 workers who were laid off and not lay off in round 2 are given below. Test the engineer's claim at 1% level of significance. Note that the data for two samples are in different column.

In 2019 Chicago Hope Hospital hired new nurses from two top universities in the country. After one year, the hospital conducts a simple study to analyse whether there is a significant difference in regard to the performance of the nurses who graduated from the two universities. Considering the maximum performance score of 100, the following is the result of independent sampling of the nurses’ performance scores. Assume the scores are not normally distributed. Table attached Question: What statistical method can be applied for this study? Explain your answer
