Please do not give solution in image formate thanku The textbook suggests 20-25% of the data used for forecasting should be used as the hold-out sample. Why might you want to use significantly more or significantly less data as your hold-out? What considerations go into determining hold-out length?

Using the JMP Output above, respond to the following prompts: Determine what measure of center and spread would be appropriate to use when analyzing the data. Explain your reasoning. State the values for your chosen measure of center and spread.  Determine which graph would be appropriate to use for the measures of center and spread you selected.

An analyst tested a forecasting model and identified the following performance metrics. What do the results tell you about the errors in the forecasting model? Be as descriptive as possible, given the results.

PART 3   A car mat manufacture been having quality issues with its production.  A series of tests were carried out to measure the resulting pH of the most common carpet produced, Type 1, as a good indicator of quality. For the following questions show all calculations and formula used.   What is the mean, mode and range of the pH after dyeing? Table – Type 1 pH after addition of dye 5.105 to 5.3 5.305 to 5.5 5.5.05 to 5.7 5.705 to 5.9 5.905 to 6.1 6.105 to 6.3 6.305 to 6.5 No. of samples 1 5 7 8 7 4 1     For pH after addition of dye calculate the standard deviation, showing your calculations in full.   Plot the standard deviation graph in Excel showing the distribution.   From your calculations and the data   Give the minimum and maximum limits the pH may be, given that the distribution is normal. Calculate the probability that a randomly selected carpet sample will have a PH of (i) 6.1 and (ii) 5.4.   Further tests were carried on a…
