To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer's adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

A serious side effect of allergy medicines is that they cause drowsiness, which can cause many problems for the individuals taking them. In recent years, a new non-drowsy allergy medicine has been developed. The company that created the medicine claims to be the first, once-a-day, non-drowsy allergy medicine (call it Medicine A). An independent research group wanted to check on this claim by comparing medicine A with another allergy medicine not advertised as non-drowsy (call it Medicine B). A random sample of 3,193 allergy sufferers was selected and each individual was randomly assigned to take either Medicine A or Medicine B. From the Medicine A group, 114 of 1,604 reported drowsiness and from the Medicine B group, 155 of 1,589 reported drowsiness. Calculate and label the two sample proportions separately. Next, calculate the difference between these sample proportions by subtracting (Medicine A – Medicine B). Complete these calculations by hand, label each of them, and…
The Transform 66 Outside the Beltway project, scheduled to be completed late 2022, is an expansion of the current highway that will provide new travel choices for drivers and hopefully congestion relief from the Capital Beltway (I-495) to Gainesville for a 22.5 mile stretch. This 22.5 mile stretch of I-66 will go through both Fairfax County and Prince William County. VDOT had team members from the project reach out through a phone survey for a random selection of 3,500 residents from both Fairfax County and Prince William County. One question asked on the survey was “Do you feel that the new I-66 Express Lanes will bring congestion relief?” Of the Fairfax County residents surveyed, 1,642 agreed they thought that the expansion will bring congestion relief while only 1,576 of the Prince William County residents surveyed agreed with the statement. 1) What is a possible confounding variable that might have introduced sampling bias intothe results of the survey? Answer in one to two…

Mr. Dela Cruz can take either two roads to the airport from his home (Road A or Road B). Owing to varying traffic conditions that travel times on two roads are not fixed, rather on a Friday around noon that travel times across these roads can be approximated per normal distribution as follows: Road A: μ = 54 minutes and σ = 5 minutes. Road B: μ = 57 minutes and σ = 10 minutes. Which road should he choose if on Friday noon he must be at the airport within 50 minutes to pick up his wife?
To the Internal Revenue Service (IRS), the reasonableness of total itemized deductions depends on the taxpayer’s adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on Adjusted Gross Income (AGI) and the Reasonable Amount of Itemized Deductions (RAID) are as follows: AGI : 22, 27, 32, 48, 65, 85, 120 RAID : 9.6, 9.6, 10.1, 11.1, 13.5, 17.7, 25.5 The correct interpretation of the meaning of each of the coefficients in the linear model is: a. When AGI is zero, the RAID is $4680 in this linear model. Since x = 0 is not included in the sample values of the independent variable, this interpretation cannot be a meaningful one. For every one thousand dollar of the AGI, the RAID increases by $161 in this linear model.…
