Answer:

$28.80

Step-by-step explanation:

Find 20% of original price (original price = $48)

  1. $48 = 100% --- divide both sides by 5 to reach 20%
  2. 100% / 5 = 20% and $48 / 5 = $9.60
  3. 20% = $9.60 (this is the price that Juan thinks is the price he should pay)

Find the price that the store is charging

  1. $48 - $9.60 = $38.4
  2. Store price (including the 20% discount)= $38.4

Find the difference in prices between Juan and the storre

  1. subtract Juan from store price
  2. $38.4 - $9.60 = $28.8

When n=343 college students are randomly selected and surveyed, it is found that x=110 own a car. Find a 99% confidence interval
Liono4ka [1.6K]

Answer:

The margin of error will be "0.65". A further explanation is provided below.

Step-by-step explanation:

The given values are:

n = 343

x = 110

At 99% confidence level,

\alpha = 1-99%

  =1-0.99

  =0.01

then,

\frac{\alpha}{2} =\frac{0.01}{2}

  =0.005

or,

Z_{\frac{\alpha}{2} }=Z_{0.005}

     =2.576

Now,

The point estimate will be:

⇒  \hat{P}=\frac{x}{n}

⇒      =\frac{110}{343}

⇒      =0.321

or,

⇒  1-\hat{P}=1-0.321

⇒            =0.679

The margin of error will be:

⇒  E=Z_{\frac{\alpha}{2} }\times \sqrt (\frac{(\hat{P}\times (1 - \hat{P})) }{n} )

On substituting the above values, we get

⇒      =2.576\times \sqrt{\frac{0.321\times 0.679}{343} }

⇒      =2.576\times \sqrt{\frac{0.217959}{343} }

⇒      =0.065

hence,

⇒  \hat{P}-E

⇒  0.321-0.065

⇒  0.256,0.386
