25,078 43,337 23,941 43,588 53,617 31,876 36,717
(a) Is the dealer's mean significantly greater than the national average of 29,452 miles for 2-year leases? Using the 10 percent level of significance, choose the appropriate hypothesis.
H0: μ ≤ 29,452 miles vs. H1: μ > 29,452 miles, reject H0 if tcalc > 1.3250
H0: μ ≥ 29,452 miles vs. H1: μ > 29,452 miles, reject H0 if tcalc > 1.3250
H0: μ ≤ 29,452 miles vs. H1: μ < 29,452 miles, reject H0 if tcalc > 1.3250
H1: μ ≤ 29,452 miles vs. H0: μ > 29,452 miles, reject H0 if tcalc > 1.3250

it established new limitations on use and disclosure for marketing purposes, prohibited selling medical information, expanded individuals’ rights to accessing their own information, and to obtain restrictions from certain disclosures of protected heath information to health plans.

of the three mortgage options that demarco and tanya have to choose from, the balloon payment mortgage would be their best option, over adjustable payment and fixed payment plans.ultimately, the balloon payment plan would save demarco and tanya overall, in interest, would cost less monthly, and they would only have to make these payments for 8 years, opposing to 30 years for adjustable or fixed payment plans. 

overall, demarco and tanya would save $80,811 if they chose balloon payments over fixed payments, and would save $116,711 if they choose balloon payments over adjustable payments. benefits with choosing fixed payments over adjustable payments is that, in the end, the payments will still be $836.30 a month, while with adjustable payments, the initial monthly payments will be $763.38 to $1082.70 a month, ultimately leading to a more costly purchase. benefits with choosing fixed payments over balloon payments are not present. benefits in choosing adjustable payments over is that it has a lower interest rate, and starts with lower monthly payments initially. benefits in choosing adjustable payments over balloon payments include a lower interest rate, and lower initial monthly payments. benefits in choosing balloon payments over fixed payments include lower interest rates, lower overall price, lower monthly payments, takes less time to pay off, and does not require a downpayment. benefits in choosing balloon payments over adjustable payments include, lower monthly payments (when averaged), takes less time to pay off, and lower overall price.

hence, option c, balloon payments, is the best option for demarco and tanya to make this purchase, for it will save them a minimum of $80811, and a maximum of $116,711.
