A quality control department of a computer manufacturing firm found compares production data in two production units A and B. In the last 10 days, UnitA has averaged 10 computers/day, with a standard deviation of3 computers/day. Over the same period, Unit B averaged 9.5 computers/day, with a standard deviation of 2.5 computers/day. At the 0.05 significance level, can we conclude that there is more variability in the number of computers produced per day in Unit A? (b) For the F-distribution underlying the test, how many degrees of freedom for the numerator do we have? How many degrees of freedom for the denominator do we have? What is the critical value (rounded to 2 decimal places)? What is the value of the test statistic
