A frozen food company that makes burritos currently has employees making burritos by hand.
They are considering purchasing equipment to automate the process and want to determine if the
automated process would result in a lower standard deviation of burrito weights. They take a
random sample from each process as shown below.
Process 1 (automated) Process 1(by hand)
n1 = 8
s1 = 0.17 ounces
n2 = 10
s2 = 0.2 ounces
Test the claim at 0.05 level of significance.

Question 2.
The number of computer malfunctions per day is recorded for 600 as follows:


# of malfunctions Frequency
0 150
1 50
2 150
3 or more 250

total

Test the goodness of fit for an appropriate model that could be Poisson distributed with a mean
of 1.5 malfunctions per day. Conduct the appropriate hypothesis test using a significance level
equal to 0.05. Interpret the results
