Chapter 14.3, Problem 26E
Contamination of various food products is an ongoing problem all over the world. The article “Prevalence and Quantitative Detection of Salmonella in Retail Raw Chicken in Shaanxi, China” (J. of Food Production, 2013) reported the following data on the occurrence of salmonella in chicken of three different types: (1) supermarket chilled, (2) supermarket frozen, and (3) wet market fresh slaughtered.
| # Salmonella Positive Samples | |||
| Type | 1. | 60 | 27 |
| 2. | 60 | 32 | |
| 3. | 120 | 45 |
Does it appear that the incidence rate of salmonella occurrence depends on the type of chicken? State and test the appropriate hypotheses using a significance level of .05.

A major company in the Montreal area, offering a range of engineering services from project preparation to construction execution, and industrial project management, wants to ensure that the individuals who are responsible for project cost estimation and bid preparation demonstrate a certain uniformity in their estimates. The head of civil engineering and municipal services decided to structure an experimental plan to detect if there could be significant differences in project evaluation.
Seven projects were selected, each of which had to be evaluated by each of the two estimators, with the order of the projects submitted being random. The obtained estimates are presented in the table below.
a) Complete the table above by calculating: i. The differences (A-B) ii. The sum of the differences iii. The mean of the differences iv. The standard deviation of the differences
b) What is the value of the t-statistic?
c) What is the critical t-value for this test at a significance level of 1%?…

Radelet and G. Pierce reported a logistic prediction equation for the death penalty verdicts in North Carolina. Let Y denote whether a subject convicted of murder received the death penalty (1=yes), for the defendant's race h (h1, black; h = 2, white), victim's race i (i = 1, black; i = 2, white), and number of additional factors j (j = 0, 1, 2). For the model logit[P(Y = 1)] = a + ß₁₂ + By + B²², they reported = -5.26, D â BD = 0, BD = 0.17, BY = 0, BY = 0.91, B = 0, B = 2.02, B = 3.98.

The savings obtained for each group of buyers are presented in the pdf that i sent: For this problem, we assume that the samples are random and come from two normal populations of unknown but equal variances.According to the theory, the average saving of buyers adopting a competitive strategy will be lower than that of buyers adopting a cooperative strategy.a) Specify the population identifications and the hypotheses H0 and H1…arrow_forward
