The F-statistic F= S21/ S22 is calculated from samples of sizes n1=10 and n2 =8.
a) What is the upper 5% critical value for this F?
b) In a test of equality of standard deviations against the two-sided alternative, this statistic has the value F= 3.45. Is this value significant at the 10% and 5% level?
