- 7Scenario: Suppose participants complete an experiment where ads are presented subliminally during a task (e.g., Pepsi ads are flashed at a very fast rate during movie ads). Participants are then given a recognition test for images of the ads, where two images are presented and participants must choose which one of the two was presented earlier. Both men and women (18 of each gender) participate in the study, and the researcher predicts that recognition accuracy (0 — 100%) will differ based on gender. Question: What is the scale of measurement of the dependent variable in this scenario? Nominal Ordinal Scale cannot determineA Gallup Poll in June 2019 asked 1015 randomly sampled adults living in the United States about their beliefs on how humans originated. Here is a table of their responses: Response Count (1) Humans evolved with God guiding 335 (2) Humans evolved but God had no part in the 223 process (3) God created humans in their present form 406 (4) Other/No opinion 51 Ten years prior, 32% of U.S. adults believed that humans evolved with God guiding, 15% believed that humans evolved but God had no part in the process, 46% believed that God created humans in their present form, and 7% believed something else or had no opinion. Has the distribution of beliefs changed since 2009?
- Disease A was reported by local area hospitals in beginning in December 28, 1998.Initial symptoms were mainly bloody diarrhea, fever, weakness. Some later had fainting, hypotension.It was traced back to a potluck holiday party held in December 23 at a paper products sales company of 256 employees. All the employees attended that holiday party.One person died. The rest made full recoveries. No one who recovered from the illness showed any further symptoms. All data from the hospitals were compiled into the following chart: Date #cases Comment12/23/1998 0 Date of the holiday party.12/24/1998 0 12/25/1998 012/26/1998 012/27/1998 012/28/1998 212/29/1998 412/30/1998 812/31/1998 16 First patient in ICU for sepsis.1/01/1999 32 Second patient in ICU for sepsis.1/01/1999 30 The first patient expired in ICU.1/02/1999 26 The second patient transferred to regular ward.1/03/1999 18 The second patient discharged to home.1/04/1999 21/05/1999 01/06/1999 01/07/1999 0 21) What is the incubation period…Your friend asks you to explain how the product rule for in-dependent events differs from the product rule for dependent events.

- 1. A machine can be in one of four states: 'running smoothly' (state 1), 'running but needs adjustment' (state 2), 'temporarily broken' (state 3), and 'destroyed' (state 4). Each morning the state of the machine is recorded. Suppose that the state of the machine tomorrow morning depends only on the state of the machine this morning subject to the following rules. • If the machine is running smoothly, there is 1% chance that by the next morning it will have exploded (this will destroy the machine), there is also a 9% chance that some part of the machine will break leading to it being temporarily broken. If neither of these things happen then the next morning there is an equal probability of it running smoothly or running but needing adjustment. • If the machine is temporarily broken in the morning then an engineer will attempt to repair the machine that day, there is an equal chance that they succeed and the machine is running smoothly by the next day or they fail and cause the machine…Is the national crime rate really going down? Some sociologists say yes! They say that the reason for the decline in crime rates in the 1980s and 1990s is demographics. It seems that the population is aging, and older people commit fewer crimes. According to the FBI and the Justice Department, 70% of all arrests are of males aged 15 to 34 years†. Suppose you are a sociologist in Rock Springs, Wyoming, and a random sample of police files showed that of 34 arrests last month, 27 were of males aged 15 to 34 years. Use a 10% level of significance to test the claim that the population proportion of such arrests in Rock Springs is different from 70%. State the null and alternate hypotheses. H0: p = 0 .7; H1: p < 0.7 H0: p ≠ 0.7; H1: p = 0.7 H0: p < 0 .7; H1: p = 0.7 H0: p = 0.7; H1: p ≠ 0.7 H0: p = 0.7; H1: p > 0.7 What sampling distribution will you use?

Suppose you are a sociologist in Rock Springs, Wyoming, and a random sample of police files showed that of 33 arrests last month, 27 were of males aged 15 to 34 years. Use a 5% level of significance to test the claim that the population proportion of such arrests in Rock Springs is different from 70%. a) What is the value of the sample test statistic? (Round your answer to two decimal places.) b) Find the P-value of the test statistic. (Round your answer to four decimal places.)
