A peony plant with red petals was crossed with another plant having streaky petals. A nurseryowner states that 75% of the offspring resulting from this cross will have red flowers. To test thisclaim, 100 seeds from this cross were collected and germinated, and 67 plants had red petals.What hypotheses should you use to test the nursery owner's claim?Ho: p = .75 vs. Ha: p * .75Ho: p = .67 vs. Ha: p = .67O Ho: p.75 vs. H₂: p= .75Ho: p ≥.75 vs. Ha: p < .75Ho: p ≤.75 vs. Ha: p > .75OA4.DWP

Your company uses a pre employment of the test to screen applicants for the job of repairman.the test is passed by 60%of the applicants.Among those who pass the test 80% complete training successfully. In an experiment,a random sample of applicant who do not pass the test is also employed. Training is successfully completed by only 50%of this group.if no pre Employment test is used,what percentage of applicants would you expect to complete training successfully?
Sleep researchers were trying to understand the impact of cell phone use before bedtime on the amount of time it took a person to fall asleep. Using a matched pairs design, they chose 8 subjects and recorded the amount of time it took the subject to fall asleep, both when using the cell phone up to attempting to sleep and stopping using the cell phone 2 hours prior to attempting to sleep, in random order. The amount of time for each person for each attempt is recorded in the table below. Person 1 2 3 4 5 6 7 8Until Attempt 22 17 45 15 35 19 36 18Two Hours Prior 18 18 40 8 23 15 32 12Difference a.

Does artistic ability determine which type of operating system a person prefers? Suppose that a market research company randomly selected n = 259 adults who used a desktop or laptop outside of the workplace (tablets and smartphones were excluded). The subjects were asked to identify the operating system of the desktop or laptop they used the most. The operating systems were classified as Windows, Mac OS, and Linux. There were no other operating systems reported in the survey. The subjects were administered a test for creative imagery ability (TCIA), and based on the results, were classified as being exceptionally artistic or not. Exceptionally artistic was defined as being above the third quartile (the top 25 percent) of all people who took the TCIA. The table contains the results of the study.

Ecologists conducted a study to investigate the potential ecological impact of golf courses. Investigators monitored the reproductive success of bluebirds in birdhouses at nine golf courses and ten similar birdhouses at nongolf sites. Data on nests in birdhouses occupied only by bluebirds are shown in the table.

An article summarizes a report of law enforcement agencies regarding the use of social media to screen applicants for employment. The report was based on a survey of 738 law enforcement agencies. One question on the survey asked if the agency routinely reviewed applicant's social media activity during background checks. For purposes of this exercise, suppose that the 738 agencies were selected at random, and that you want to use the survey data to decide if there is convincing evidence that more than 25% of law enforcement agencies review applicants' social media activity as part of routine background checks. (a) The sampling distribution of p describes the behavior of p when random samples are selected from a particular population. Describe the shape, center, and spread of the sampling distribution of p for samples of size 738 if the null hypothesis Ho: p = 0.25 is true. (Round your answers to three decimal places.) The sampling distribution of p is ---Select--- O; and has mean Hp and…

A researcher takes a sample of 50 individuals and administers a background check to identify the number of prior arrests for each person. For whatever reason, one person is removed from the analysis and another random person is selected to replace that person. Having no additional information, what is your best guess of the number of prior arrests experienced by the replacement person? Why?
Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct. If two different subjects are randomly selected without replacement, find the probability that they both lied.

You are hiking through the woods, and come across some tracks; based on your expe- rience, you estimate there is a 40% chance the tracks are from a dog, a 30% chance the tracks are from a wolf, a 20% chance the tracks are from a coyote, and a 10% chance the tracks are from some other animal. Your friend, also a nature lover, notices some white hairs in the tracks. They know that 20% of dogs have white hair, 50% of wolves have white hair, 10% of coyotes have white hair, and 30% of other animals in the area have white hair. What are the odds of these tracks coming from a dog, wolf, coyote, or other animal?
In a survey, each participant indicated how much they agreed with the statement, "Hard work is the way to get what you want in life." Which of the following would you expect to have zero correlation, or close to zero correlation, with the response to the above statement? A) Agreement with the statement, "Happiness mostly depends on luck." B) Conscientiousness score on a personality inventory test. C) High school GPA. D) A random number between 0 and 10, chosen by the participant.
A study was performed to test eyewitness accuracy. Ten pairs of participants entered a room believing they would be participating in a gambling experiment. Each participant was given $10 in coins to play poker with. The participants were randomly seated near the door or away from the door. After 15 minutes, an actor dressed in street clothes burst into the room and stole the money from the participant near the door. The “thief” was later caught, and both participants (the victim and the witness) were asked to identify him in a line-up. Eyewitness accuracies from the participants were then compared. The ten victims reported a mean accuracy of 31.5 (SD = 21). The witnesses had a mean accuracy of 52.2 (SD = 19.5). Was there a difference? What was the effect size of eyewitness accuracy? Show the nul and alternative hypthoesis, aplhpa level 0.05 and test the null hypothtesis and draw the rejctin line, conclusion and effect size
