I need help solving these ANOVA problems

6 In conjunction with the housing foreclosure crisis, many economists expressed increasing concem about the level of credit card debt and efforts of banks to raise interest rates on these cards. The banks claimed the increases were justified. A government sub-committee decided to determine if the average credit card balance depends on the type of credit card used. Under consideration are five credit cards. The sample sizes to be used for each level are 27, 26, 26, 20, and 23, respectively. Comple parts a through f below a. Describe the parameter of interest for this analysis. Choose the correct answer below. A. The average credit card balance of card holders of the five credit cards B The type of credit credit card held by credit card customers C. The five types of credit cards under examination D. The standard deviation of credit card balances of card holders of the five credit cards b. Determine the factor associated with this experiment. Choose the correct answer below. O A. The average credit card balance of card holders of the five credit cards OB. The type of credit credit card held by credit card customers OC. The five types of credit cards under examination OD.

A company produces treadmills for use in exercise clubs and recreation centers. The treadmill motors are purchased from an outside vendor. Currently, the company is considering which motor to include in its new treadmill series. Three potential suppliers have been identified. The company has decided to make its decision based on how long a motor operates at a high level of speed and incline before it fails. A random sample of 10 motors of each type is selected, and each motor is tested to determine how many minutes (rounded to the nearest minute) it operates before it needs to be repaired. Use the accompanying sample information for each motor to complete parts and b. 7 Click the icon to view the sample data. 7 Outside vendor.

Mineral oil-based dielectric fluids have been used more extensively than other dielectric fluids. Their only shortcomings are their relatively low flash and fire point. One study examined the fire point of mineral oil, high-molecular-weight hydrocarbon (HMWH), and silicone. The fire points for each of these fluids are recorded in the following table.
