Tju [1.3M]

Answer:

She need 7 kg 400 g of sugar more to complete this order of cookies.

Step-by-step explanation:

Given:

Stevie Baker received 15 kg 700 g of sugar. The production manager noticed that they needed 23 kg 100 g of sugar to make the order of cookies she just received.

Now, to find the quantity of sugar she need to complete this order of cookies.

Quantity of sugar Stevie Baker received = 15 kg 700 g.

Quantity of sugar needed to make the order = 23 kg 100 g.

Now, to get the quantity of sugar she need to complete this order of cookies we subtract quantity of sugar Stevie Baker received from quantity of sugar needed to make the order:

$23\ kg\ 100\ g-15\ kg\ 700\ g$

$=7\ kg\ 400\ g.$

Therefore, she need 7 kg 400 g of sugar more to complete this order of cookies.

A Pew Research study finds that 23% of Americans use only a cell phone, and no land line, for making phone calls (The Wall Stree

azamat

Answer:

We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %

Step-by-step explanation:

A pew research finds that 23 % ( μ ) of Americans use only cell phone

Sample Information

sample size n = 200

x₁ = 51 then p₁ = 51/200 p₁ = 0,255

and q₁ = 1 - p ₁ q₁ = 1 - 0,255 q₁ = 0,745

Sample big enough for the approximation of the binomial distribution to the normal distribution

p₁*n = 0,255 * 200 = 51 > 5 and q₁*n = 0,745* 200 = 149 > 5

Test hypothesis

Null hypothesis H₀ p₁ = μ = 0,23

Alternative hypothesis Hₐ p₁ ≠ 0,23

Is a two tail test. We choose CI = 95 % then significance level is α = 0,05 %

α = 0,05 as is a two tail test α/2 = 0,025

from z-table z(c) = 1,96

To calculate z(s) = ( x - μ ) /√p₁*q₁/n

z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200

z(s) = 0,025 / 0,0308

z(s) = 0,81

Comparing z(s) and z(c)

z(s) < z(c) 0,81 < 1,96

Then z(s) is in the acceptance region: we accept H₀

Taya2010 [7]

Answer:

The point estimate of the proportion of people over 6ft to total people is 6:25

Step-by-step explanation:

To find this, simply start with the number of people over 6 ft and total people as a proportion.

12:50

Then simplify by dividing by 2

6:25
