Concept explainers

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Question

The Chamber of Commerce in a Canadian city has conducted an evaluation of 300 restaurants in its
metropolitan area. Each restaurant received a rating on a 3-point scale on typical meal price (1 least
expensive to 3 most expensive) and quality (1 lowest quality to 3 greatest quality). A crosstabulation of the
rating data is shown below. Forty-five of the restaurants received a rating of 1 on quality and 1 on meal price,
42 of the restaurants received a rating of 1 on quality and 2 on meal price, and so on. Thirty of the
restaurants received the highest rating of 3 on both quality and meal price.

in this Canadian city. Let x = quality rating and y = meal price.
(b) Compute the expected value and variance for quality rating, x.
(c) Compute the expected value and variance for meal price, y.

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating.

State H0 and what is H1 for all of them a, b and c a) The marketing researcher would like to find out whether consumers from different regions evaluate brand A differently when they see the brand name b) The marketing researcher would like to find out whether consumers from the south region and the north region evaluate brand B differently when they see the brand name c. The data file contains four taste evaluations. The taste evaluations were measured on a scale from 1 to 10 (with 10 the highest evaluation). Brand equity of one brand for one respondent is the difference of branded score and unbranded score of that brand evaluated by the respondent. The marketing researcher would like to find out whether brands A and B have brand equity, in other words, whether the evaluation of brand A (B) is different when consumers can see the brand name vs. when they cannot see the brand name.

A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. 1. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure? A. Repeated-measures t-test B. One-way Independent Measures ANOVA C. Repeated-measures ANOVA D. Independent-measures t-test 2. State the hypothesis that aims to test the consumer group’s research goal (i.e., what is H0 and HA).
