Question

1.Were your two estimates the same? Did the mean length of all the straws in the bag change in between selecting the two samples? Explain your reasoning.
2.The actual mean length of all of the straws in the bag is about 2.37 inches. How do your estimates compare to this mean length?

3.If you repeated the same process again but you selected a larger sample (such as 10 or 20 straws, instead of just 5), would your estimate be more accurate? Explain your reasoning.

Sample 2 mean = 3.8
