According to the Internal Revenue Service (IRS), the taxpayer's adjusted gross income determines the
appropriateness of total itemised deductions. For taxpayers with high adjusted gross incomes, significant
deductions, like as charitable and medical deductions, are more justifiable. The data on adjusted gross
income and the average of justifiable itemised deductions is shown in Table 1 (in thousand of dollars).

a)
Obtain the regression model for data in Table 1 and interpret the value.
b)
Estimate the total itemized deductions for a taxpayer with an adjusted gross income of $52, 500.
Calculate the r correlation and interpret the value. Justify whether other method can be applied to
evaluate the correlation.

* Agraduate student in psychology wanted to look into the influence of gender on the percelved
riskiness of risk behaviors as well as on the frequency of participation in risk behaviors. The
mean scores for the risk behaviors are recorded in the table below.

In a sample of 232 women, 44 had elevated cholesterol levels. Can you conclude that the proportion of people with elevated cholesterol levels differs between men and women? Use the a= 0.05 level. Show all your work including finding the test statistic and a graph showing the location of both the test statistic and the critical value.arrow_forwardAtul gets a pocket money allowance of Rs. 12 per day. Thinking that this was rather 1ess, he asked his friends about their allowances and obtained the following data which includes his allowance also – (amounts in Rs.). 12, 18, 10, 5, 25, 20, 22, 15, 10, 10, 15, 13, 20, 18, 10, 15, 10, 18, 15, 12, 15, 10, 15, 10, 12, 18, 20, 5, 8, 20. He presented these data to his father and asked for an increase in his allowance as he was getting less than average amount. His father, a statistician, countered pointing out that Atul's allowance was actually more than the average amount. Reconcile these statements.arrow_forward

- 24. The Graduate Record Exam is a standardized test taken by many graduating college seniors. GRE scores are often included in applications to masters or doctoral programs. Suppose that a psychology major received a score of X = 160 on the verbal section of the GRE and a score of X = 159 on the quantitative section of the GRE. The mean verbal GRE score for the years 2014–2017 among psychology majors was M = 152, s = 7. The mean quantitative score for the same years was M = 149, s = 7. Use z-scores to describe the student's performance relative to other psychology majors.

- 1. A researcher is interested in the relationship between test anxiety and study time on test performance. Test anxiety, defined as a type of anxiety that is triggered by the anticipation or experience of taking tests, was measured on a 0-100 scale via a Test Anxiety Questionnaire (higher scores indicating greater/more anxiety). Study time, defined as the amount of time a student devoted to studying/reviewing material for the test, was measured in hours (spent studying/reviewing material). Test performance was the test score students received on the test, out of 100 marks. Assume an alpha level of .05. If there are issues with the data file images and they can't be copied, PLEASE just explain how the questions would be answered, no need to physically use jamovi. a) Assuming a linear relationship between all three variables of interest, request a correlation matrix from jamovi and comment on the strength, direction, and significance of all three zero-order correlation coefficients…arrow_forwardPLEASE ANSWER ALL THE PARTS OF THE QUESTION ( THIS IS NOT A GRADED ASSIGNMENT )arrow_forward25.
