Question:

Programming. A student is using a computer program to estimate the parameters for his model by fitting in different sets of initial values. He determines that his program needs different amounts of time (in minutes) to estimate the parameters. He selects 12 different sets of initial values and records the time used to get the estimated parameters as follows:image text in transcribed

a) Plot the data. Are any of the observations outliers?
Explain.

b) Find a 95% confidence interval for the true mean. If another student used the same program to estimate parameters with an average running time of 25 minutes, what can you conclude about this? If there are outliers, find intervals with and without the outliers present. Explain.
