question 6 (1 point)\nof the past 450 orders on a website, 126 people returned to leave feedback on their purchase. based on these results, how many would the site expect to leave feedback out of 2400 orders?\n607\n670\n672\n700
Answer
# Explanation:
## Step1: Calculate the feedback - rate
The feedback - rate is the ratio of the number of people who left feedback to the total number of orders in the past. The formula for the feedback - rate $r$ is $r=\frac{n_1}{N_1}$, where $n_1 = 126$ is the number of people who left feedback and $N_1=450$ is the total number of orders. So, $r=\frac{126}{450}=0.28$.
## Step2: Estimate the number of feedbacks for new orders
We use the feedback - rate to estimate the number of people who will leave feedback for $N_2 = 2400$ orders. The formula is $n_2=r\times N_2$. Substitute $r = 0.28$ and $N_2=2400$ into the formula: $n_2=0.28\times2400 = 672$.
