In swimming, clearly you would like to swim fast, but swimming consistent times is also important. A survey of 34 swims by men on a local university's swim team found a variance of their swimming times was 6 seconds. A similar survey of 28 swims by swimmers at a different university found the variance was 9 seconds. When testing the hypothesis (at the 5% level of significance) that the variances are equal, what is the test statistic?

the answer is c.

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
