Answer:
a. 185
b. 158
c. By adding the cost of redwood, the mean goes up because of how significantly high the tree is. The larger number raises the entire thing.
Step-by-step explanation:
a. to find the mean, you add all the numbers together then divide by the amount of numbers you added. so by adding them all together we get 1,110. since we added 6 numbers, we divide the sum by 6. our answer is 185.
b. for this we are doing exactly the same as A, except were taking out the 320. we add all our numbers (again, except the redwood) and get 790. since we only added 5 numbers this time, we divide by 5. this is how we get our mean of 158.
