Hi please do not answer the questions if you are not sure, It will mean a lot to me. Also when possible show the calculations/work for the particular problem.

Thank you.

The expenses and income of an individual are given in table form. Find the net monthly cash flow (it could be positive or negative). Assume salaries and wages are after taxes, that 1 month = 4 weeks, and that 1 year = 12 months. Round your answer to the nearest dollar. 6) Income Expenses Salary: $32,000/year House payments: $1700/month Jewelry sales: $350/month Groceries: $120/week Household expenses: $360/month Car insurance: $480 semiannually Donations: $500/year Miscellaneous: $800/month A) -$445 B) -$405 C) -$85 D) - $766 7) Solve the problem. 7) Suppose you start saving today for a $8000 down payment that you plan to make on a condo in 4 years. Assume that you make no deposits into the account after your initial deposit. The account has quarterly compounding and an APR of 6%. How much would you need to deposit now to reach your $8000 goal in 4 years? A) $6893.39 B) $5893.39 C) $6304.25 D) $5969.40 8) Answer the question. 8) Double blinding is used in an experiment to avoid which of the following problems? A) If the patient knows that he received the placebo and not the treatment he may be angry and fail to tell the truth B) If the researcher knows that the patient received the treatment, the researcher may also experience health changes C) If improvement is observed in a patient, it is difficult to know whether this is due to the treatment or the placebo effect D) If an experimenter knows whether the patient has received the treatment or the placebo, this may influence how he or she questions the patient 9) Use the guidelines to evaluate the study. From the information given, what is the biggest flaw in the study? 9) A pharmaceutical company conducted a study to test the effectiveness of its new anti-depression medication. 500 adults suffering from depression were selected at random and were randomly assigned to either a treatment group or a placebo group. The experiment was double blind. The results were analyzed by the company. A) Variables are difficult to define/measure B) Confounding variables C) The source of the study D) Selection bias E) The setting may not encourage honest responses Construct a line chart for the data. 10) The ages of employees of a company are summarized in the frequency table. 10) Age Frequency 18-24 11 25-31 38 32-38 35 39-45) 27 46-52 22 53-59 14 60-66 5 h A) B) Freq Fred 45+ 45+ 40+ 40+ 35+ 35+ 30+ 30+ 25+ 25+ 20+ 20+ 15+ 15+ 10+ 10+ 5+ 5+ + 35 + 49 + 42 + 56 28 42 56 21 63 28 35 49 63 Age (years) Age (years) D) None of the above Freq 45+ 40+ 35+ 30+ 25+ 20+ 15+ 10+ 5+ + 42 + 49 + 56 21 28 35 63 Age (years)
