Comment on the role that the number of observations plays in resistance. A.

As the sample size increases, the impact of the misrecorded data on the mean decreases.

B.

As the sample size increases, the impact of the misrecorded data on the mean remains the same.

C.

As the sample size increases, the impact of the misrecorded data on the mean increases.

As the sample size increases, the impact of the misrecorded data on the mean decreases.

Step-by-step explanation:

The size of an experiment is very important in a research. Large experimental size with many sample unit helps to minimize error this is because the error is shared among all the samples but when an experimental unit is small the error is usually high.

As sample sizes increases the number of misrecorded data on the mean decreases this is because error is usually spread across all samples in a large sample size and the mean is the average performance of the samples.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
