Answer:
The treatments (new menu item) were not randomly assigned to the students - option B.
Step-by-step explanation:
A choice was given to each student to select between the macaroni and cheese and the Cajun potato barrels. Therefore, the treatments were not randomly assigned to the students, and students who prefer their food will select that item and give high ratings. Hence, the study suffers from selection bias.
The reason below prevents this study from being a well-designed experiment;
The treatments (new menu item) were not randomly assigned to the students - option B.
Total cash inflow is how much cash is coming in
15 hrs a week at 8.25 per hr......15 * 8.25 = 123.75 per week
30 a week from the hair salon
so thats (123.75 + 30) = 153.75 per week
there are 52 weeks in a year..
so total cash inflow for the year is : (153.75 * 52) = $ 7995 <==
cash outflow is how much cash is leaving..
185.65 per month for the car...there are 12 months in a year...so this
cost is (185.65 * 12) = 2227.80
65 a month on gas...65 * 12 = 780
plus the 575 yearly for insurance
for a total cash outflow of : (2227.80 + 780 + 575) = $ 3582.80 <==
