Question
Chapter 11.2, Problem 61E
To determine
To explain: the study is related to observational study or experimental study.
Expert Solution & Answer
Answer to Problem 61E
The study is the experimental study.
Explanation of Solution
Given information:
The data is given below as,
Observational study:
If the individuals under the study are just observed and measured based on certain characteristics without modifying them then the study is termed as observational study.
Experimental Study:
If some treatments are applied on the individuals in order to observe the effectiveness of the treatments then the study is termed as experimental study.
A study is conducted to determine whether answers of the respondents are being affected if the rating scale is changed or not. For this a simple random sample of 90 students are selected from the total population of 1:000 students. The first 45 students are given the scale of l to 5 and the remaining 45 students are given scale of 0 to 4.
In this study: the different scaling is given to two groups of students for observing the effect of scale on the responses to the question. This shows that: the study is an experiment.
Thus, the study is experimental study.

- 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.

- You want to obtain a sample to estimate the proportion of a population that possess a particular genetic marker. Based on previous evidence, you believe approximately p∗=11% of the population have the genetic marker. You would like to be 90% confident that your estimate is within 0.5% of the true population proportion. How large of a sample size is required?n = (Wrong: 10,603) Do not round mid-calculation.
