A local fertility specialist noticed that some of her patients were heavy coffee drinkers. She wanted to know if there was any association between coffee drinking and conception in the first year of trying. She asked a random sample of 40 patients (some of whom have successfully become pregnant) about coffee drinking. The table below summarizes the data (table entries represent raw frequencies of women in terms of pregnant or not and coffee drinker or not). Using alpha =.01, use the 2-way Chi-square to determine whether there is any relation between successful pregnancy and coffee drinking.

Coffee

Yes (drinker)

No (no-drinker)

Pregnant

Yes (pregnant)

6

15

Not (not pregnant)

The appropriate discount rate for the deli expansion is 9.3​% and the appropriate discount rate for the wine section is 8.8​%. What are the MIRRs for the Singing Fish Fine Foods​ projects? What are the MIRRs when you adjust for unequal​lives? Do the MIRR adjusted for unequal lives change the decision based on​ MIRRs? ​Hint: Take all cash flows to the same ending period as the longest project.

If the appropriate reinvestment rate for the deli expansion is 9.3​%, what is the MIRR of the deli​ expansion? _________​% ​(Round to two decimal​ places.)

If the appropriate reinvestment rate for the wine section is 8.8%, what is the MIRR of the wine​ section? ________% ​(Round to two decimal​ places.)

Steve is considering donating his personal car, a red Ford Mustang, to a qualified charity. He purchased it for $7,000 5 years ago but it has a fair market value of $12,000. The charity would sell the car and use the proceeds to help sick children. What amount would Steve be able to claim as a charitable contribution deduction if he donates the car?

(In response to comment for more info) There is no depreciation rate, the fair value has actually gone up, regardless this information is not needed for this problem and neither is the market interest rate.)

Compile the following C code to MIPS assembly.

a. Assume that i and j are stored in register $s1 and $s2, respectively. i = i – 2 + j;

b. Assume base address of Array B and the variable i are stored in registers $s3 and $s1, respectively. B[1] = (B[0] x 4) - I;

Explain each step in detail!

my professor has the following answer: 1) addi $t0, $s1, -2 add $s1, $$t0, $s2

2) lw $t0, 0 ($s3) #load B[0] into a register sll $t0, $t0, 2 #shift left logical A[2] x 4 #(may have several different ways) sub $t0, $t0, $s1 # (B[0] x 4) - i sw $t0, 4($s0)

Can you explain in detail why?
