3) Flexography is a printing process used in the packaging industry. The process is popular, since it is costeffective and can be used to print on a variety of surfaces (for example, paperboard, foil, and plastic). A study was conducted to determine if flexography exposure time has an impact on the quality of the printing. Four different exposure times were studied: 8, 10, 12, and 14 minutes. A sample of 35 print images were collected at each exposure time level, for a total of 140 print images. The measure of print quality used was dot area (hundreds of dots per square millimeter). The data with partial results shown in the table complete parts a and g. Partial ANOVA Table a. The subjects are randomly assigned to the treatment groups. What is the design type? b. Identify the dependent (response) variable and treatments for the design. c. Identify the treatments for the design. d. Set up the null and alternative hypotheses of the test. e. What is the test statistic for the test to compare the mean shell thickness for the four housing systems? (Round to three decimal places as needed.) f. Identify the p-value for the test to compare the mean shell thickness for the four housing systems. g. State the conclusion for the test to compare the mean shell thickness for the four housing systems
