Answer:The population will be 198000 people

Step-by-step explanation: 5.5% of 240,000 = 13200

Therefore in 15 years time the population will be 13200×15 years = 198,000 people.

Answer:

<h2>=3,798,000 people</h2>

Step-by-step explanation:

<h2>if 100%=240,000</h2><h2>therefore 100+5.5=105.5%</h2><h2>105.5÷100×240,000</h2><h2>=253,000</h2><h2>15×253,000</h2><h2>=3,798,000</h2>

Anna found the difference between thirteen and the product of four and a number. Which expression represents this phrase, and wh
Elan Coil [88]
The first thing we must do for this case is to define a variable.
 We have then:
 n: unknown number.
 We write the algebraic expression:
 13 - 4n
 For n = 3 we have:
 13 - 4 (3) = 13 - 12 = 1
 Answer:
 
An expression that represents this phrase is:
 
13 - 4n
 
its value if n = 3 is:

The Pew Research Center reported that 73% of Americans who own a cell phone also use text messaging. In a recent local survey, 1
AnnZ [28]

Answer:

z=\frac{0.775 -0.73}{\sqrt{\frac{0.73(1-0.73)}{200}}}=1.433  

Now we can find the p value. Since we have a bilateral test the p value would be:  

p_v =2*P(z>1.433)=0.152  

Since the p value is higher than the significance level of 0.1 we have enough evidence to FAIL to reject the null hypothesis and the best conclusion for this case would be:

Do Not reject H0

Step-by-step explanation:

Information provided

n=200 represent the sample size slected

X=155 represent the cell phone owners used text messaging

\hat p=\frac{155}{200}=0.775 estimated proportion of cell phone owners used text messaging

p_o=0.73 is the value to verify

\alpha=0.1 represent the significance level

We need to conduct a z test for a proportion

z would represent the statistic

p_v represent the p value

System of hypothesis

We want to verify if the true proportion of cell phone owners used text messaging is different from 0.73 so then the system of hypothesis are:

Null hypothesis:p=0.73  

Alternative hypothesis:p \neq 0.73  

The statistic to check this hypothesis is given by:

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

Replacing the data given we got:

z=\frac{0.775 -0.73}{\sqrt{\frac{0.73(1-0.73)}{200}}}=1.433  

Now we can find the p value. Since we have a bilateral test the p value would be:  

p_v =2*P(z>1.433)=0.152  

Since the p value is higher than the significance level of 0.1 we have enough evidence to FAIL to reject the null hypothesis and the best conclusion for this case would be:

Do Not reject H0
