Chapter 2.5, Problem 194E
a.
To determine
Write the meaning of the positive association between given two variables.
Explain the reason why the positive relationship makes sense in the given context.
b.
To determine
Write the meaning of the negative association between the given two variables.
Explain the reason why the negative relationship makes sense in the given context.
c.
To determine
Draw a
Check whether there is a positive or negative relationship.
Check whether there are any outliers. If any outliers are present, then indicate the country associated with each outlier and describe the characteristics that make it an outlier for the scatterplot.
d.
To determine
Check whether it appears that that the remaining countries have a positive or negative relationship between the two variables if outliers are eliminated from the scatterplot.
e.
To determine
Find the
Check whether the correlation is affected by the outliers.
f.
To determine
Check whether it can be concluded that faster connection speed causes people to spend more time online.

The following relates to Problems 4 and 5.
Christchurch, New Zealand experienced a major earthquake on February 22, 2011. It destroyed 100,000
homes. Data were collected on a sample of 300 damaged homes. These data are saved in the file called
CIEG315 Homework 4 data.xlsx, which is available on Canvas under Files. A subset of the data is
shown in the accompanying table. Two of the variables are qualitative in nature: Wall construction and
roof construction. Two of the variables are quantitative: (1) Peak ground acceleration (PGA), a measure
of the intensity of ground shaking that the home experienced in the earthquake (in units of acceleration of
gravity, g); (2) Damage, which indicates the amount of damage experienced in the earthquake in New
Zealand dollars; and (3) Building value, the pre-earthquake value of the home in New Zealand dollars.

- Rose Par posted Apr 5, 2025 9:01 PM Subscribe To: Store Owner From: Rose Par, Manager Subject: Decision About Selling Custom Flower Bouquets Date: April 5, 2025 Our shop, which prides itself on selling handmade gifts and cultural items, has recently received inquiries from customers about the availability of fresh flower bouquets for special occasions. This has prompted me to consider whether we should introduce custom flower bouquets in our shop. We need to decide whether to start offering this new product. There are three options: provide a complete selection of custom bouquets for events like birthdays and anniversaries, start small with just a few ready-made flower arrangements, or do not add flowers. There are also three possible outcomes. First, we might see high demand, and the bouquets could sell quickly. Second, we might have medium demand, with a few sold each week. Third, there might be low demand, and the flowers may not sell well, possibly going to waste.
