Suppose a random sample of n measurements is selected from a binomial population with probability of success p = .39. Given n =
Oksi-84 [34.3K]

Answer:

The answer is below

Step-by-step explanation:

a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.

b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.

\mu_x=\mu=np=300*0.39=117

c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:

\sigma_x=\sqrt{np(1-p)} =\sqrt{300*0.39(1-0.39)} =8.44

The balcony of an apartment is 4 feet by 7 feet. On a scale drawing of the apartment, the balcony is 0.8 inch by 1.4 inches, and
-Dominant- [34]

Answer:

The actual dimensions of the kitchen are 12\ ft by 14\ ft

Step-by-step explanation:

step 1

Find the scale  of the drawing

To find the scale , remember that is equal to the ratio of  the corresponding dimension in the drawing divided by the corresponding actual dimension

so

\frac{0.8}{4}\frac{in}{ft}=0.2\frac{in}{ft}

step 2

To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale

so

2.4\ in=2.4/0.2=12\ ft

2.8\ in=2.8/0.2=14\ ft
