Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Suppose that 40% of all supermarkets in the US use recyclable plastic bags. We would like to assess if the proportion of supermarkets in Michigan that use recyclable plastic bags is more than the stated rate. For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________

Consider the patients who went to the Urgent Care at the local hospital last week as the observational units (people we are studying) in a statistical study. a) Identify two categorical/qualitative variables that could be recorded on these observational units. b) Identify two numerical/quantitative variables that could be recorded on these observational units. c) State a research question that you could investigate about these observational units, using at least one of the variables that you gave in part a) and b).
Consider the following scenario and answer the questions below: The ornithologist decided to investigate the effect of temperature on the migration of North American birds. Develop a hypothesis in the appropriate format. Identify the independent variable. Identify the dependent variable. Plan an investigation (what would she do to collect data?). Did she engage in basic science or applied science? Explain. Did she engage in inductive or deductive reasoning? Explain
The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
ANOVA. Dr. Milgramm is conducting a patient satisfaction survey, rating how well her patients like her on a scale of 1-10. Her patients tend to fall into three categories: “Like a lot”, “like somewhat”, and “dislike a lot”. She believes that she might get different satisfaction scores from people in each group, but (because she's not great at numbers) she wants you to do an ANOVA to be sure. She has collected data from 12 patients (three equal groups) with the following results. Group 1) “Like a lot” Mean: 8 SS: 2 N: df: Group 2) “Like somewhat” Mean: 5 SS: 6 N: df: Group 3) “Dislike a lot” Mean: 2 SS: 4 N: df: Grand Mean: df Within-Group:__________ df Between-Groups:___________ Estimated Variance (S21) for Group 1: _______ Estimated Variance (S22) for Group 2: ___________ Estimated…
What statistical test would a researcher use to test the following research hypothesis: Individuals who report less favorable attitudes toward the police are more likely to be sentenced to higher security prisons. Attitudes measured as 1 = very favorable, 2 = somewhat favorable, 3 = somewhat not favorable, and 4 = not at all favorable. Sentences measured as 1 = minimum, 2 = medium, and 3 = maximum.
The success of an airline depends heavily on its ability to provide a pleasant customer experience. One dimension of customer service on which airlines compete is on-time arrival. The file LateFlights contains a sample of data from delayed flights showing the number of minutes each delayed flight was late for two different airlines, Delta and Southwest. Click on the datafile logo to reference the data. DATA file Southwest 120 29 67 89 115 a. Formulate the hypotheses that can be used to test for a difference between the population mean minutes late for delayed flights by these two airlines. 141 = population mean minutes late for delayed Delta flights 142 = population mean minutes late for delayed Southwest flights Ho 141 142 : Delta 113 36 113 82 26 - Select your answer - 0 Southwest 49 56 31 110 141 df = p-value = We - Select your answer-reject Ho.

The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable. Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.

Read the scenario below to determine which one of the five areas of construct validity (content, response processes, internal consistency, relationship to other variables and consequences) is of most concern. Researchers developed a new and different exam for admission into graduate school. Researchers constructed a Table of Specifications for the new exam.
