Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,
Sedaia [141]

Answer:

The  confidence interval is  0.304 <  p  < 0.324

Step-by-step explanation:

From the question we are told

      The sample proportion \r p  =  0.314

      The margin of error  is E =  0.01

The confidence interval for  p is mathematically represented as

       \r p -  E  <  p  < \r p + E

=>    0.314 -  0.01  <  p  < 0.314 +  0.01

=>   0.304 <  p  < 0.324

A laptop has a listed price of $703.98 before tax. If the sales tax rate is 9.25% , find the total cost of the laptop with sales
Jlenok [28]

Answer:

<h2>The cost of the laptop is $769.10</h2>

Step-by-step explanation:

In this problem we are required to find the cost of the laptop when 9.25% of the cost is added as tax

we are given that the tax rate is 9.25% of the initial cost

and the initial cost is $703.98

 let us calculate 9.25% of  $703.98

(9.25/100)* 703.98= 0.0925*703.98= $65.12

Hence the charges for tax is $65.12

The total cost of the laptop when tax is included is

the initial cost Plus the tax charges= $703.98+$65.12= $769.098

$769.10
