document.write( "Question 1206152: In swimming, clearly you would like to swim fast, but swimming consistent times is also important. A survey of 32 swims by men on a local university's swim team found a variance of their swimming times was 6 seconds. A similar survey of 27 swims by swimmers at a different university found the variance was 10 seconds. When testing the hypothesis (at the 5% level of significance) that the variances are equal, what is the test statistic? (please round your answer to 2 decimal places, show work) \n" ); document.write( "

i think they're talking f test for equal variance.
\n" ); document.write( "i used the f test calculator at https://www.statskingdom.com/220VarF2.html

\n" ); document.write( "\n" ); document.write( "you are looking for difference in variance, but the input requires standard deviation, so you need to enter the square root of the variance.
\n" ); document.write( "square root of 6 = 2.449489743.
