A researcher studying the effect of price cuts on consumers' expectations makes up two different histories of the store price of a hypothetical brand of laundry detergent for the past year. Eight students in a class view one or the other price history on a computer. Some students see a steady price, whereas others see regular sales that temporarily cut the price. Students are asked the price they would expect to pay. The names of the eight subjects follow. 1. Franklin 2. James 3. Wright 4. Edwards 5. Rust 6. Walsh 7. Gofberg 8. Williams

The experimental units areA. all business students at the college. B. the eight business students who participated. C. the business students who were in the fluctuating price group. D. the price they would expect to pay.

.B. the eight business students who participated

Step-by-step explanation:

The experimental units are entities (objects, animals, people) on which an experiment is performed. For example testing the efficiency of a particular treatment on four sick goats. in this case the four sick goats are the experimental units.

For the case above, the eight business students who participated in the experiment are the experimental units.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
