Answer:

The standard deviation of the uniform distribution is:

σ=(b−a)/√12

U(3, 12)

σ = (12−3)/√12 = 9/√12 = 2.5981

U(80, 250)

σ = (250−80)/√12 = 170/√12 = 49.0748

U(4, 93)

σ = (93−4)/√12 = 89/√12 = 25.6921

A sporting good store is offering an additional 30% off all clearance items and she purchases a pair of running shoes on clearan

Talja [164]

Answer:

Total discount = $39.50

or 46.47 %

Step-by-step explanation:

First we need to figure out what she will pay for the shoes. She is getting 30 percent off the 65 dollars.

Discount = price * percent off

= 65*.3

= 19.50

The cost of her shoes is the price minus the discount.

Cost = 65- 19.5

= 45.50

To find the total discount, take the original price and subtract the final cost.

Total discount = 85-45.50

= 39.50

To find the total percent discount, we use the formula

total percent discount = (original - final)/original * 100

= (85- 45.50)/85 * 100

= 39.5/85*100

= 46.47%

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,

⇒ $\hat{P}-E$

⇒ $0.321-0.065$

⇒ $0.256,0.386$
