- Part e & d pleaseBackground information: Allison collected additional days of data to monitor the process. Steps to monitor using the control charts: Now monitor the process. An additional ten days of data have been collected, see table labeled “1st 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 1st 10 days of monitoring. Plot the data for the 1st 10 days on the Xbar and R charts. Is the process in control? If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart. Now that we have set up the control charts using enough data from a stable process, the 30 days of data, we will monitor the process. While monitoring the process, what will we use as the upper control limit for the R (range) Chart to compare against our new range values? Enter your response to three decimal places. You do not need to include the units (minutes), ONLY the numeric value.

(See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32. The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment? Briefly explain your answer. A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas…
- please answer quicklyThe relative effectiveness of two different sales techniques was tested on 12 volunteer housewives. Each housewife was exposed to each sales technique and asked to buy a certain product, the same product in all cases. At the end of each exposure, each housewife rated the technique with a 1 if she felt she would have agreed to buy the product and a 0 if she probably would not have bought the product.

Use the image for question 10. 10. A hair stylist used market research to learn that members of different age groups have different preferences for positive and negative advertisements. Research participants could mark their preference for only one of the two ads. The positive ad presented a model with attractive hair supported by a message affirming the decision to schedule hair styling services, whereas the negative ad displayed a model with unattractive hair supported by a message describing the need for hair styling services. Results are shown in the table below: What is the probability of a site visitor either preferring negative ads or being a member of age category B? 6% 62% 56% 68% 93% 11. A hair stylist averaged 21 clients per day over the past several months. Typically four of these clients have been male. What is the probability for the total number of female clients the hair stylist can expect…
- You have the following data: Student A took 2 courses in the Fall semester. His previous CGPA was 3.2. He received GPA 3.5 in the Fall semester. Student B took 5 courses in the Fall semester. Her previous CGPA was 3.9. She received GPA 3.6 in the Fall semester. Student C took 4 courses in the Fall semester. His previous CGPA was 3.6. He received GPA 3.4 in the Fall semester. Using this data, we'll try to build a model using Least Square approximation, that can predict the CGPA of a student in the Fall semester given the number of courses s/he took in Fall, and his/her previous CGPA. (In real life, we'd use many more parameters, but for the sake of the quiz, we are keeping things simple.) The model is as follows - wi x (number of courses) + wz x (previouos CGPA) = GPA in Fall Find the values of wi, and wz using Least Square approximation. (Round off up to 3 decimal points) w, is equal to - wz is equal to - If a student took 4 courses in Fall, and his previous CGPA was 3.7, what would be…I have attached the picture for review.

- Please do not give solution in image format thankuYou are a manager for Company ABC and decide to compile data and analyze your employees’ level of satisifaction. You create a survey to ask each employee to rate their level of satisfaction working at Company ABC. Table 1 shows data of 15 people employees that responded to your survey. Each of the employees have the same job title: Sales Representative. The data set includes variables regarding an employee ID, gender, ethnicity, region, pay rate, employee satisfaction rating. Each employee was asked to rate their level of satisfaction working at Company ABC. A composite score from 0 (lowest) to 5 (highest) is shown as the data variable employee satisfaction.
