A TA in statistics thinks that the format of the conferences and the timing of the assignments may affect students'assignment marks (out of 10). He decided to design three conferences with a different format: (1) with lecturing, (2) withdemonstrating problems, and (3) with involving students in active problem-solving. Twelve students attended one of theconferences (four in each format) and asked to submit their assignments at week 3. Another twelve students attendedone of the conferences but asked to submit their assignments at week 5. The data are tabled below:Assignment Week 3Week 5Lecture6,7,5,75,5,4,5FormatDemo problems7,8,8,96,7,7,6Active problems9,10,10,108,9,9,10Note: ΣΣΣx=1385Perform the ANOVA test and table the results, stating all critical values. State and explain what should be the follow-upanalysis after the overall F-test if any (NO calculation but just explain).

Here, we have to perform ANOVA test and then conclude results from the test.

Katy is interested to understand the of herd immunity concept for Singapore's COVID-19 cases. She noted that 95% of adult population in Singapore is fully vaccinated by the end of October 2021. She want to compare difference of COVID-19 death cases in Singapore before Singapore achieve herd immunity and after Singapore achieve herd immunity. She collects the data of death cases in Singapore two weeks in the early of October 2021 (to represent before herd immunity) and two weeks in the end of No (Ctrl) -21 (to represent after herd immunity). Assume the variable is approximately normally distributed. The data are presented as below.

An und Tuate student performed a visual experiment on a number of participants. Since the experiment involved displays of colored letters and backgro after the experiment the student wondered whether the presence or absence of color vision in the participants could have produced some of the effects seen in the data. The student went back, tested his participants for colorblindness, and reanalyzed the data. He considered the variables color vision of participant ("colorblind" or "not colorblind") and trial outcome ("hit", "miss", "false alarm", or "correct rejection"). The contingency table below gives a summary of the data from 2000 trials of the experiment. Each of the trials was performed either by a colorblind participant or a non-colorblind participant. Each cell of the table contains three numbers: the first number is the observed cell frequency (f); the second number is the expected cell frequency (f) under the assumption that there is no dependence between the two variables…
Researchers conducted a study to find out if there is a difference in the use of online-learning by different age groups. Randomly selected participants were divided into two age groups. In the 16 to 29-year-old group, 7% of the 628 surveyed use online-learning, while 11% of the 2,309 participants 30 years old and older use online learning. (Set 1 for 16-29 year old group; Set 2 for 30 years old and older). Decision and conclusion: Reject the null hypothesis or do not reject the null hypothesis?
A global research study found that the majority of today's working women would prefer a better work-life balance to an increased salary. One of the most important contributors to work-life balance identified by the survey was "flexibility," with 41% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women. d.) If a sample of 400 is taken how does this change your answer to b? The probability that in the sample between 37% and 47%say that having a flexible work schedule is either very important or extremely important to their career success is____.
A college president wanted to know how 10-year-after-graduation salaries for aca- demic majors (English, psychology, math, etc.) compared to salaries for career-oriented majors (business, engineering, computer science, etc.). She matched 84 academic majors at her college with 84 career-oriented majors on the basis of SAT scores and GPA. She found MAcademic = $59,250, MCareer =$61,000, sD = 9,500. Use an alpha of .05 and a two-tailed test to determine if there is a difference in salaries.
You have two groups of researchers getting data on a new drug for Alzheimer’s patients with working memory loss. Both researchers give the same memory task performed using the Wisconsin Card Sorting Task and count the number of correct answers from 15 patients each.The results of Researcher A are: 60, 62, 70, 55, 78, 53, 78, 53, 70, 66, 62, 79, 51, 65, 69The results of Researcher B are: 68, 75, 71, 65, 58, 74, 68, 72, 60, 59, 72, 65, 70, 72, 69Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.
A national study found that treating people appropriately for high blood pressure reduced their overall mortality by 20%. Treating people adequately for hypertension has been diffcult because it is estimated that 50% of hypertensives do not know they have high blood pressure, 50% of those who do know are inadequately treated by their physicians, and 50% who are appropriately treated fail to follow this treatment by taking the right number of pills. Answer the following questions ( please answer all the parts 1,2 and 3): 1) What is the probability that among 10 true hypertensives at least 50% are being treated appropriately and are complying with this treatment?2) What is the probability that at least 7 of the 10 hypertensives know they have high blood pressure? 3) If the preceding 50% rates were each reduced to 40% by a massive education program, then what effect would this change have on the overall mortality rate among true hypertensives; that is, would the mortality rate decrease…
I need to see if I am doing these problems correctly. I am more of a handwritten person so if you can show me how to write these out I would appreciate it for our teacher only shows us how to use a calculator. Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 15 randomly selected patients who went to the emergency room at rural hospitals waited an average of 5.9 hours to be admitted into the hospital. The standard deviation for these 15 patients was 1.4 hours. What can be concluded at the the αα = 0.05 level of significance level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should…
13. For each of the following studies, make a chart of the four possible correct andincorrect decisions, and explain what each would mean. (Each chart should belaid out like Table 6-1, but put into the boxes the possible results, using thenames of the variables involved in the study.)

(b) A study of whether high school students who receive an AIDS preventionprogram in their school are more likely to practice safe sex than are otherhigh school students. (c) A study of whether memory for abstract ideas is reduced if the informationis presented in distracting colors.

9. A group of 50 single men were asked which dating apps they had on their phones. The follo data were collected: 33 of the men had the Tinder app. 30 of the men had the Coffee Meets Bagel app. 26 of the men had the Hinge app. 16 of the men had both the Tinder and Coffee Meets Bagel apps. 14 of the men had both Tinder and Hinge apps. 18 men had both Hinge and Coffee Meets Bagel apps. 7 men had all three apps on their phones. a) Represent this information in a Venn diagram: b) Calculate the number of single men who have none of these apps on their phone. c) How many single men only had Tinder on their phone? d) How many students own at most two of the apps?
A social and personality psychologist thinks that creativity differs by personality traits, rather than the traditional view that it is a cognitive process. Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2. Using the 0.05 alpha level, are introverts more creative than extroverts? Use all of the steps of hypothesis testing. extrovert introvert 8 18 7 17 11 10 3 14 5 16 8 15 7 19 4 12
