Select the correct option(s). Note that there might be multiple correct options.1.Why is training error generally lower than validation error even onlarge randomly split datasets?:A. Training data are always casier than validation data.B. Models tend to fit to noise present in the training set but not in the valida-tion set (increasing variance).C. Models tend to lack the ability to fit relationships on the training dataset(increasing bias).D. This does not happen in practice.

Training Error: In statistical modeling, data is trained to build models. Trained datasets are…

The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.4, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use ? = 0.10. State the null and alternative hypotheses. -H0: ?12 > ?22 Ha: ?12 ≤ ?22 -H0: ?12 ≠ ?22 Ha: ?12 = ?22 -H0: ?12 ≤ ?22 Ha: ?12 > ?22 -H0: ?12 = ?22 Ha: ?12 ≠ ?22 Find the value of the test statistic.

Prepare a layout and resulting analysis of variance (a) table for five types of fertilizers viz., A, B, C, D, and E and two blocking factors viz., varying soil fertility and varying seeds. Answer:
The variance in a production process is an importance measure of the quality of the process. A large variance often signals an opprotunity for improvement in the process by finding ways to reduce the process variance. The conduct a statistical test to determine whether there is a significant differeence between the variance in the bag weights for two machines. Use a 0.05 level of significance. What is your conclusion? Which machine, if either, provides the greater opportunity for quality improvements?

5.Stocks and Mutual Fund Ownership It has been found that 51.4% of U.S. households own stocks and mutual funds. A random sample of 300 heads of households indicated that 178 owned some type of stock. At what level of significance would you conclude that this was a significant difference? Use the P-value method. Assume the variable normally distributed. Use a graphing calculator. Find the P-value. At what level of significance is this a significant difference?
