The following table shows the individual measurements for five samples taken every 15 minutes starting at 10:00 am to be used in monitoring the quality of a process. 10:00 am 10:15 am 10:30 am 10:45 am 11:00 am 2.0 2.0 1.8 2.1 1.6 1.8 2.0 1.9 2.1 2.0 2.0 2.0 2.1 1.9 2.2 1.8 2.0 2.2 1.9 1.7 1. How many measurements are in each sample? 2. Suppose a mean control chart is being used with an upper limit of 2.2 and a lower limit of 1.8. Using the data above, what would be the first point to plot on the control chart?

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 40 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that o = 7.10 ml/kg for the distribution of blood plasma. When finding an 99% confidence interval, what is the critical value for confidence level? (Give your answer to two decimal places.) (a) Find a 99% confidence interval for the population mean blood plasma volume in male firefighters. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error (b). What conditions are necessary for your calculations? (Select all that apply.) n is large the distribution of volumes is normal o is unknown the distribution of volumes is uniform…

Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven. 1.) Describe each data​ set, that is determine the​ shape, center, and spread.   Sample mean for Car 1 x=enter your response here mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)   Sample mean for Car 2 x=enter your response here mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)   Median for Car 1 M=enter your response here mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)   Median for Car 2 M=enter your response here mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)   Range for Car 1 R=enter your response here mi​ / 10 gal ​(Type an integer or decimal rounded to one decimal place as​ needed.)   Range for…

The weight of a car can influence the mileage that the car can obtain. A random sample of 17 cars was taken and the weight (in pounds) and mileage (in mpg) were recorded and are in the table below. X, weight Y, mileage 4000 23.6 4000 23.4 2500 40.9 3500 28 2750 46.9 3000 32.2 3000 31.4 4500 17.2 2250 38.9 3500 31.3 3500 32.6 2750 36.3 5500 13.2 3000 31.4 3500 31.3 2250 53.3 3500 28 a) The symbol and value of the correlation coefficient are as follows:     Round final answer to 2 decimal places.     Select an answer r R² ρ ŷ y p̂ X̄ p μ σ s  =      Interpret this value: There is a strong Select an answer positive negative  Select an answer linear quadratic bell-shaped uniform  relation between weight and mileage for cars. b) The symbol and value of the coefficient of determination are as follows:     Select an answer Fail to Reject the Null Accept the Null Reject the Null
