Answer:

Answer is B) control group

Step-by-step explanation:

Survey is when you ask questions to a group of people. Has nothing to do in this case. Correlational does not exist but correlation means the association between two groups.

In an experiment, you apply a treatment, or a conditions that differentiates groups and measure an outcome . In this case the treatment is drinking alcohol to measure memory. The group that receives the treatment is the experimental group and the one that not receives the treatment is the control because, we are comparing or controlling alcohol consumption in this group to measure differences in memory with the experimental group.

Jean Gray earns a graduated commission of 4% on her first $2000 of sales and 8% on all sales over $2000. Jeans sales for the pas
Ahat [919]

Jean Gray's total earnings over the past week was $3,925

Since Jean earns 4% for the first $2,00 business she does, she earns a base commission of = $2,000*0.04 = $80

Now, we need to find how of additional sales did Jean do over and above the base of $2,000. This is calculated as follows:

Total Sales = 3,925

Base sales =2,000

Add-on sales = 3,925-2,000 = 1,925

For the $1,925 sales, Jeans earns 8% commission, her commission for this will be 1,925*0.08 = $154

So, the total commission = $80 + $154 = $234

Her commission for the week was $234
