Random samples of size 64 are taken from an infinite population whose mean and standard deviation are 24 and 6.4, respectively.
umka2103 [35]

Answer:

Mean 24, standard error 0.8

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation, also called standard error s = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 24, \sigma = 6.4, n = 64

What are the mean and the standard error of the sample mean?

By the Central Limit Theorem, mean 24 and standard error s = \frac{6.4}{\sqrt{64}} = 0.8

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (
Alenkinab [10]

Answer:

Width = 20\ in

Area = 400\ in^2

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

Height = 31\ in + 9\ in

Height = 40\ in

The width which is half the height is:

Width = \frac{1}{2} * Height

Width = \frac{1}{2} * 40\ in

Width = 20\ in

The area is:

Area = \frac{Height * Width}{2}

Area = \frac{40\ in * 20\ in}{2}

Area = 40\ in * 10\ in

Area = 400\ in^2
