Let M represent the cost of a whiteboard marker.
10(3M + $2.75) = $177.50
3M + $2.75 = $17.75
3M = $15
M = $5
Hence, each whiteboard marker cost $5.
Answer: approximately normal
Step-by-step explanation:
1/2 Thinking about population shape and sample size
When a population is normally distributed, the sampling distribution of the sample mean x will also be normal regardless of sample size.
Since the distribution of distances is normal, the sampling distribution of the sample mean distance will also be normal.
2/2 Answer
The sampling distribution of the sample mean distance will be approximately normal.
