You measure 33 turtles' weights, and find they have a mean weight of 48 ounces. Assume the population standard deviation is 14.1 ounces. Based on this, construct a 90% confidence interval for the true population mean turtle weight.

Confidence interval = 48±4

Step-by-step explanation:

Given:

Mean X = 48

Standard deviation sd = 14.1

Computation:

Z table value of 90% = 1.645

Total number n = 33

Computation:

Margin of error M.E = Z[sd/√n]

Margin of error M.E = 4 approx.

Confidence interval = 48±4

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

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
