A study was commissioned to find the mean weight of the residents in a certain town. The study examined a random sample of 121 residents and found the mean weight to be 194 pounds with a standard deviation of 36 pounds. Determine a 98\% confidence interval for the mean, rounding all values to the nearest tenth.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
