A population has mean 128 and standard deviation 22
A. Find the mean and standard deviation of
for samples of size 36.
B. Find the probability that the mean of a
sample of size 36 will be within 10 units of
the population mean, that is, between 118
and 138. Chint, since the samples are over
30, CLT states that it is normal and we can
use normalcdf)

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Which of the following are accepted without proof in a logical system? check all that apply.

The clayton family’s pool has vertices at the coordinates (0, 2), (0, 5), (2, 5), (2, 6), (5, 6), (5, 1), (2, 1), and (2, 2). if each grid square has an area of 9 square feet, what is the area of the pool?
