Hypothesis Testing of Genetically Modified Foods

Design (but not do) a test to see if genetically modified foods are different from non-genetically modified (NGM) foods. Assume you are designing a study that will analyze GM and NGM foods, and answer the following questions. 1. What will your null and alternative hypotheses be? (Hint: Ensure your null and alternative hypo

Nonparametric Hypothesis Test

Using the research question and data below conduct a equivalent nonparametric test of hypothesis below. The hypothesis for the ANOVA test is: H0: μ1=μ2=μ3=μ4=μ5=μ6=μ7=μ8=μ9 (all means are equal) H1: Not all means are equal (at least one is different) Telecommunication Servi

Hypothesis Testing by the Wall Street Journal

The wall street journal reported 28% of people who bank online have cut back on their internet use. A credit union's manager is certain that while internet use may be down, it is much less than 28% of its customers.

Hypothesis Testing

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,000 per year. To test her hypothesis, she collected a simple random sample of 100 starting clerical salaries from across the state and found that the sample mean is $29,750. 1: State the appropriate n

Hypothesis Testing for Relevant Critical Values

Provide the relevant critical value for each of the following circumstances: 1: HA: μ > 13, n = 15, σ = 10.3, Level of Significance = 0.05 2: HA: μ =/ 21, n = 23, s = 35.40, Level of Significance = 0.02

Mean salary of accountants

Is the mean salary of accountants who have reached partnership status higher than that for accountants who are not partners? A sample of 15 accountants who have the partnership status showed a mean salary of $82,000 with a standard deviation of $5,500. A sample of 12 accountants who were not partners showed a mean of $78,000 wi

A Hypothesis Test for a Single Population Mean

Please conduct a hypothesis test for a single population mean of a quantitative variable equal to a given number. For example, test the hypothesis that the population mean of the intrinsic is equal to 5 or not. Use all 25 data rows. Since n<30, use a t statistic. For this and any hypothesis test, number the five steps

Five step hypothesis testing

1) What are the five steps involved in classic hypothesis testing? 2) In general, what is a "Critical Value" or "Cut-Off Score" of a test statistic? What are the critical values of z for a two-tailed test (.05)? What are the critical values of z for a one-tailed test (.05)? What are the critical values of z for a two-

Test Value - Criminal Proceedings

Some defendants in criminal proceedings plead guilty and are sentenced without a trial, whereas others who plead innocent are subsequently found guilty and then are sentenced. In recent years, legal scholars have speculated as to whether sentences of those who plead guilty differ in severity from sentences for those who plead i

Hypothesis testing on low-frequency data

Indoor natatoriums or swimming pools are noted for their pool acoustical properties. The goal is to design a pool in such a way that the average time that it takes a low-frequency sound to die is at most 1.3 seconds with a standard deviation of at most .6 seconds. Computer simulations of a preliminary design are conducted to see

Hypothesis test/classical approach

The problem: In Meijer supermarket, the customer's waiting time to check out is approximately normally distributed with a standard deviation of 2.5 minutes. A sample of 25 customer waiting times produced a mean of 8.2 minutes. Is this evidence sufficient to reject the supermarket's claim that its customer checkout time averag
