To determine if their 14 oz filling machine is properly adjusted, Harvey Soft Drinks has decided to use an X-Chart which uses the range to estimate the variability in the sample. Answer Table Step 4 of 7: Use the following sample data, taken from the next time period, to determine if the process is "In Control" or "Out of Control".

A researcher studies water clarity at the same location in a lake on the same dates during the course of a year and repeats the measurements on the same dates 5 years later. The researcher immerses a weighted disk painted black and white and measures the depth (in inches) at which it is no longer visible. The collected data is given in the table below. Complete parts (a) through (c) below Observation 1 2 3 4 5 6 1/25 3/19 5/30 7/3 9/13 11/7 41.6 72.7 72.4 65.9 64.2 68.6 49.3 72.1 76.6 69.4 69.8 70.5 Date Initial Depth, X, Depth Five Years Later, Y, a) Why is it important to take the measurements on the same date? CA. Using the same dates makes it easier to remember to take samples. B. Using the same dates maximizes the difference in water clarity. OC. Those are the same dates that all biologists use to take water clarity samples. D. Using the same dates makes the second sample dependent on the first and reduces variability in water clarity attributable to date. b) Does the evidence…

Tune current between one and six years old were randomly selected from the classified ads of the Arizona republic.The following data were obtained where X donates age in years,and y donates price,in hundreds of dollars. x (age) 6,6,6,2,2,5,4,5,1,4 price(100ths) 270,260,275,405,364,295,335,308,405,305 Draw a scatter diagram. Find the linear correlation coefficientr. describe the shape strength and direction.does a linear relationship exist between the age of Corvette and its price (use the critical value to explain).If appropriate explain the slope in contexts. If appropriate explain the Y intercept in context.Predict the price of a one year old Corvette.Find the residual of a one year old Corvette.
Linear Regression Problem (See the data table) Please refer to the table on the last page to answer this problem The table displays the average global temperature in degrees celcius relative to the year 2000 in five year intervals. What relationship are you interested in studying? Identify the independent and dependent variables. How many data points were collected? Was sampling conducted? Draw a bubble diagram showing the relationship between the variables, include the effects of a confounding variable on your diagram.
