The weights of a random sample of 10 firs ants was the following ( in milligrams):
1.2 3.1 3.9 2.3 3.4 8.0 4.8 3.9 1.9 7.1
a) Use the data to find a point estimate of the population mean weight of fire ants. What estimator did you use?
b) Use the data to find a point estimate of the population variance. What estimator did you use?
c) Use the data to find a point estimate of the population standard deviation. What estimator did you use?
d) Create a 90% confidence interval for the mean weight of fire ants.
