Aresearcher reports that the time (in minutes) it takes children who are "picky eaters" to finish their vegetables is negatively skewed, with children finishing their vegetables in 4.2±1.0 (m±sd) minutes. based on chebyshev's theorem, we can conclude that68% of children finished their vegetables in 3.2 to 5.2 minutes.50% of children finished their vegetables in at least 3.2 minutes.99.7% of children finished their vegetables in 2.2 to 6.2 minutes. at least 89% of children finished their vegetables in 1.2 to 7.2 minutes.

Option d) Chebyshev's rule

Step-by-step explanation:

The Chebyshev's rule state that for a data that is not distributed normally,

atleast .

Here, k cannot be 1 and is always greater than 2.

For k = 2,

of data lies within the range of

Atleast 75% of children finished their vegetables in

For k = 3,

of data lies within the range of

Atleast 89% of children finished their vegetables in

Thus, option d) is correct.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
