Hi Can You Help Me Find The Answer To This Im Not Sure What It Is class=

Sagot :

Answer

Between 39.13 s and 58.27 s

Explanation

Chebyshev's theorem states that the proportion of data that falls within k standard deviations of the mean is given as

Proportion = 1 - (1/k²)

For a proportion of 88.9%, we solve for k

0.889 = 1 - (1/k²)

(1/k²) = 1 - 0.889 = 0.111

k² = (1/0.111) = 9

Take the square root of both sides

k = 3

So, we need 3 standard deviations below the mean and above the mean

Mean = 48.7 s

Standard deviation = 3.19 s

Mean - 3(standard deviation) = 48.7 - 3(3.19) = 48.7 - 9.57 = 39.13

Mean + 3(standard deviation) = 48.7 + 3(3.19) = 48.7 + 9.57 = 58.27
