The administrator of a nursing home would like to do a time-and-motion study of staff time spend per day performing nonemergency
WINSTONCH [101]

Answer:

32 days must be sampled to test the proposed hypothesis.

Step-by-step explanation:

Consider the provided information.

The average number of person-hours per day spent on these task was \mu_0=16.

The actual value of μ is 12 hours or less i.e μ=12

She wants a test having α=0.05

The probability of a type II error of at most β=0.10 and σ=7.64.

δ = μ-μ0

   = 12-16

  = -4

Now use the formula for calculating the sample size:

N=\frac{(Z_{\alpha}+Z_{\beta})^2\sigma^2}{\delta^2}

Substitute the respective values.

N=\frac{(Z_{0.05}+Z_{0.1})^2(7.64)^2}{(-4)^2}

N=\frac{(1.6449+1.2816)^2(7.64)^2}{16}

N=31.2437958482\approx 32

Hence, 32 days must be sampled to test the proposed hypothesis.

Help please with this math question
Vanyuwa [196]
To solve this question, simply use the formula to find the volume of the cylinder,

V = Pi r^2 • h

V = 3.14 • 4^2 • 4.

Then compare the value for volume to the closest number on the number line. Is it in between 2 numbers, exactly one number on the number line or very close to one number as in the number line.

Function a(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e 6h. what
hram777 [196]

<u> </u><u>48 square inches per inch </u><u> is the average rate of change in surface </u><u>area</u><u>.</u>

What is an area in math?

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

The surface area of a cube of side length e is:

A(e) = 6 *e².

The rate of change is:

A'(e) = 2 * 6 * e

The average rate of change between 3 in and 5 in is:

r  = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in

Now, the options are given in:

"squere inches per inch"

This is written as:

in^2/in = in.

Then we can write our above rate as:

r = 48in = 48in^2/in = 48 square inches per inch.

a woman had 75 to give away she gave the first person 1/3 of it then the second person 1/5 of the balance hiw much money did she
HACTEHA [7]
75 divided by 3 is 25, so she gave the first person 25. 75 divided by 5 is 13 for the second person. 13 + 25 is 38, and 75 - 38 is 37, so she had $37 left. Hope this helps!
