Five members of the soccer team and five members of the track team ran the 100-meter dash. their times are listed in the table below: soccer track 12.3 12.3 13.2 11.2 12.5 11.7 11.3 12.2 14.4 13.7 what is the difference of the means for the two groups? 0.52 12.22 12.74 24.96

Hence, the difference in Mean of two teams is:

0.52

Step-by-step explanation:

Five members of the soccer team and five members of the track team ran the 100-meter dash.

Their time is listed as:

Soccer          Track

   12.3              12.3

   13.2               11.2

   12.5               11.7

   11.3                12.2

    14.4               13.7

The mean of the soccer team is given by:

The mean of track team is given by:

Hence, the Difference in Mean is:

Hence, the difference in Mean of two teams is:

0.52

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
