Topic 5

Product Quality

According to Black (2017), “Product quality is measurable in the product. Consumers perceive differences among products, and quality products have more attributes. For example, a personal computer with more memory has more quality. Tires with more tread have more quality”.

The text also provided information on user quality, which states the level of quality is based on the consumer. It would be in my opinion that user quality, has a great influence on products or services that are deemed high or worthy quality. In today’s technological society, consumers have the ability to quickly share their opinions or experiences on several social media platforms. This type of immediate sharing, can be of great value to a company.

Topic 6

Pearson’s Correlation Coefficient

Class,

“Originated by Karl Pearson about 1900, the correlation coefficient describes the strength of the relationship between two sets of interval-scaled or ratio-scaled variables. Designated r, it is often referred to as Pearson’s rand as the Pearson product-moment correlation coefficient. It can assume any value from −1.00 to +1.00 inclusive. A correlation coefficient of −1.00 or +1.00 indicates perfect correlation.”

Topic 8

Multiple Regression Problem and Solution

Class,

It has been hypothesized that overall academic success for college freshmen as measured by grade point average (GPA) is a function of IQ scores, X1, hours spent studying each week, X2, and one’s high school average, X3. Suppose the regression equation is . The multiple standard error is 6.313 and R2 = 0.826.

What is the predicted GPA for a student with an IQ of 108, 32 hours spent studying per week, and a high school average of 82?

3.1446??By substituting the values for each of the independent variables, the predicted GPA is 3.1446, found by 6.9 + 0.055(108) + 0.107(32) + 0.0853(82).
