The claim is that the proportion of adults who smoked a cigarette in the past week is less than 0.30, and the sample statistics

IrinaK [193]

Answer: 0.84

Step-by-step explanation:

let p be the population proportion of adults who smoked a cigarette in the past week.

As per given , we have

$H_a: p$

Sample size : n= 1491

The sample proportion of adults smoked a cigarette= $\hat{p}=\dfrac{x}{n}=\dfrac{462}{1491}=0.30985915493\approx0.31$

The test statistic for proportion is given by :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Substitute all the values , we get

$z=\dfrac{0.31-0.30}{\sqrt{\dfrac{0.30(1-0.30)}{1491}}}\\\\=\dfrac{0.01}{\sqrt{0.000141}}\\\\=\dfrac{0.01}{0.011874342087}=0.84261497731\approx0.84$

Hence, the value of the test statistic = 0.84

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1.5 m. What is th

Galina-37 [17]

We know, Surface area of a Cube = 6a²
Here, Edge length(a) = 1.5

Substitute the value,
s = 6(1.5)²
s = 6 * 2.25
s = 13.5

In short, Your Answer would be Option D

Hope this helps!

Who wants to be the brainliest? Rearrange the formula C = 2πr for r.

faltersainse [42]

Answer:

B) r= c/2 $\pi$

Step-by-step explanation:

To isolate r, divide 2 $\pi$ on both sides

c = 2 $\pi$ r

-- --

2 $\pi$ 2 $\pi$

c/2 $\pi$ =r

Please help! I need an immediate correct answer please see attachment thanks so much

MA_775_DIABLO [31]

Label the vertices A (- 3, - 2), B (- 7, - 3 ), D (- 4, - 5 )

and the centre of dilatation C (- 7, - 6 ), then

CA = a - c = < - 3, - 2 > - < - 7, - 6 > = < 4, 4 >

CA' = 3 < 4, 4 > = < 12, 12 >

A' = (- 7 + 12, - 6 + 12 ) = ( 5, 6 )

CB = b - c = < - 7, - 3 > - < - 7, - 6 > = < 0, 3 >

CB' = 3 < 0, 3 > = < 0, 9 >

B' = (- 7 + 0, - 6 + 9 ) = (- 7, 3 )

CD = d - c = < - 4, - 5 > - < - 7, - 6 > = < 3, 1 >

CD' = 3 < 3, 1 > = < 9, 3 >

D' = (- 7 + 9, - 6 + 3 ) = ( 2, - 3 )

Summarising

(- 3, - 2 ) ⇒ (5 , 6 )

(- 7, - 3 ) ⇒ (- 7, 3 )

(- 4, - 5 ) ⇒ (2, - 3 )
