According to a report on consumer fraud and identity theft, 22% of all complaints for a year were for identity theft. In that year, Ohio had 825 complaints of identity theft out of 3452 consumer complaints. Does this data provide enough evidence to show that Ohio had a higher proportion of identity theft than 22%? Test at the 1% level. State the hypotheses. Ho: p? v Ha: p|? v Calculate the test statistic. Round to four decimal places. Calculate the standardized test statistic. Round to three decimal places. Z = Find the p-value. Round to four decimal places. p-value State your decision. O Since the p-value is greater than .01, fail to reject Ho. O Since the p-value is less than .01, fail to reject Ho. O Since the p-value is less than .01, reject Họ. O Since the p-value is greater than .01, reject Ho. Interpret the results. O At the 1% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Ohio is not equal to 22%. O At the…
Can you find me an example of a grouped histogram on the internet, where the independent variable is related to some psychological topic. Please copy and paste an image of the histogram and describe it. Focus on the following: 1. what are the x-axis values (i.e. what variable is measured and what are the units)?2. what shape does the distribution have if any?3. what is the most frequent observation (can be more than one)4. What is the range (expressed as a single number)?5. what is the interval size?6. How many intervals are there?

The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.05 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference? compute the test statistic. find critical value X^2
▾ Part 1 of 4 John Paul teaches five sections of Introductory Psychology. He wants to know whether or not the average score on the second exam is the same for all five sections. John Paul's student's exam scores are listed below. Use an ANOVA test with a level of significance of 5% to test whether the average score is the same for all five sections.

Empathy among police officers influences how they interact with citizens and the likelihood that they receive complaints. Gender differences in levels of empathy in the general population are not large but male and female officers have been shown to have different interaction styles with the public; this may be due to the different empathy levels. After sampling officers and measuring their levels of empathy you find the following data. Males Females n = 6 n = 9 M = 31 M = 45 SS = 490 SS = 680 If you were going to make gender comparisons like this, which option would be the correct choice? Write A or B in the box. [a] Option A. Independent-measures t-test Option B. Repeated-measures t-test
Which of the following can lead to bias in qualitative research? Select one. Using a questionnaire that was developed by a person who has a personal belief in the issue or works for the entity involved to show only positive results Obtaining approval from the Internal Review Board before implementing the research Running a sample size through a statistical analyst to ensure the results could be generalized Ensuring the survey questions will provide data related directly to the research question
Identify the statistical procedures that are appropriate for the data. When possible identify descriptive statistics, inferential statistics and a measure of effect size There is some evidence suggesting that you are likely ton improve your test scores if you rethink and change answers on a multiple-choice item (Johnston, 1975). To examine this phenomenon, a teacher encouraged students to reconsider their answers before turning in exams. Students were asked to record their original answers and the changes that they made. When the exams were collected, the teacher found that 8 students improved their grades by changing answers only 7 students had lower grades with the changes. The teacher would like to know if this is a statistically significant result.
A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?
