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.
South Dakota prices vary $350,000: $400,000:$400,000:$425,000:$429,000: $440,000: $560,000: $585,000,: $585,000: $785,000 : $1,300,000. We found the following Mean = 569000 SD = 272703.1353 T score = .7113 P Value = .4932 We failed to reject the hypothesis. What is a 95% confidence interval and how would you create one for the population average price? What would it look like. How does this related to Central limit therorem? If you had a margin of error of $13,000 how large of sample would you need with a 90% confidence interval using the given tscore.

stion 3 It is assumed that the proportion of households that have three telephone numbers is 30%. A company have reason to believe that this proportion of households is less than 30%. A market survey of 150 households gives the results that 43 of the households have three telephone numbers. Test at 5% level of significance whether the telephone company’s belief is true

please show working out. Thank you A University has put in place a 4 week course of lunchtime exercise breaks for its staff to see if its employees’ job satisfaction can be improved. To measure the effectiveness of this program, 10 randomly selected staff in the program were surveyed about their feelings at work, once at the start of the program and again after the course. Higher scores indicate higher satisfaction. The job satisfaction index results for this group were: Staff 1 2 3 4 5 6 7 8 9 10 Before 34 28 29 45 26 27 24 15 15 27 After 33 31 36 46 32 34 28 26 19 37 Use a test of significance at 5% level to decide if the program has improved the employee’s job satisfaction on average. Show your graphical evidence, if needed, and clear conclusion. - please sketch the curve as well. thank you
