Answer:

The 94% confidence interval is : ( 0.0867 , 0.1933 ) = ( 8.67 , 19.33 )%

Step-by-step explanation:

Solution:-

- The sample size, n = 150 visitors

- The proportion of visitors who hiked, p = 0.14

- We are to create a 94% confidence interval for the population proportion.

- We will determine the Z-critical value for the CI : 0.94 or significance level α = 0.06

- The critical value is defined and plucked from Z-score (standardized) tables as:

                        Z-critical = Z_α/2 = Z_0.03 = 1.88

- The confidence interval for the population proportion (p) is constructed as:

                         ( p - Z-critical\sqrt{\frac{p*(1-p)}{n} } , p + Z-critical\sqrt{\frac{p*(1-p)}{n} } )\\\\( 0.14 - 1.88\sqrt{\frac{0.14*(1-0.14)}{150} } , p + 1.88\sqrt{\frac{0.14*(1-0.14)}{150} } )\\\\( 0.08673  , 0.19326 )

- The 94% confidence interval is : ( 0.0867 , 0.1933 ) = ( 8.67 , 19.33 )%

Please help me simplified this
Lera25 [3.4K]

For this case we have that by definition, the perimeter of the quadrilateral shown is given by the sum of its sides:

Let "p" be the perimeter of the quadrilateral, then:

p = 7 + y + 7 + x\\p = 7 + 7 + x + y\\p = 14 + x + y

So, the perimeter of the figure is: 14 + x + y

Answer:

p = 14 + x + y

Which ratios are less than 8 to 10? Check all that apply.<br> 6/20<br> 3:5<br> 50/100<br> 13:15
poizon [28]

9514 1404 393

Answer:

  6/20, 3:5, 50/100 are all less than 8/10

Step-by-step explanation:

It can help to give all the ratios a common denominator. (We'll use 100, and fudge the last one a bit.)

  8/10 = 80/100 . . . . our reference value

__

  6/20 = 30/100 . . . less than 8/10

  3/5 = 60/100 . . . . less than 8/10

  50/100 . . . . . . . . . less than 8/10

  13/15 ≈ 86.7/100 . . . more than 8/10

50 Is a(n) ________of 10 because 5×10 = 50
Svet_ta [14]

Answer:

50 Is a multiple of 10 because 5×10 = 50

Step-by-step explanation:

We want to fill in the gap in :

50 Is a(n) ________of 10 because 5×10 = 50

Recall that multiples of a number are obtained by multiplying the number by natural counting numbers.

In this case one multiple of 10 is 50.

The reason is that, we obtain 50 by multiplying 5 by 10 to get;

5 \times 10 = 50

Therefore the best complete is multiple.
