Answer:

Option (B) a 95% confidence interval does not include the hypothesized value of the parameter              

Step-by-step explanation:

Alpha, α = 0.05

We conduct a hypothesis test at 5% significance level.

The null hypothesis will be rejected when

Option (B) a 95% confidence interval does not include the hypothesized value of the parameter

  • When a 95% confidence interval is constructed,it contains all the possible values for the parameter being estimated.
  • If the value of the parameter stated in the null hypothesis is contained in the 95% confidence interval, then we fail to reject the null hypothesis 0.05 level and accept it.
  • If the value stated in the null hypothesis is not in the interval, then we fail to accept the null hypothesis and reject the null hypothesis at the 0.05 level.

We can check each of these using the Pythagorean Theorem, a^2 + b^2 = c^2
Option A: 
.5^2 + 1.2^2 = 1.3^2


.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
1^2 + 2^2 = 3^2
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
This option works
Option D:
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work

Degger [83]

Answer:

Step-by-step explanation:

\frac{3x + 5}{2x + 7} = 5

do cross multiplication

3x + 5 = 5(2x + 7)

3x + 5 = 10x + 35

5 - 35 = 10x - 3x

-30 = 7x

-30/7 = x

20 A

since there are 7 angles given it means that the polygon is heptagon as heptagon has 7 sides.

sum of interior angle of heptagon = (n-2)*180

(7-2)*180

5*180

900

Now ,

110 + 90 + 150 + 102 + 110 + 170 + x = 900

732 + x = 900

x = 900 - 732

x = 168 degree

20 B

since 5 angles are given it means that the polygon is pentagon as pentagon has 5 sides.

sum of interior angles of a pentagon = (n-2)*180

(5-2)*180

3*180

540 degree

Now ,

110 + 95 + 120 + 114 + x = 540

465 + x = 540

x = 540 - 465

x = 75 degree

21

let one rational number be x

according to the question,

1/7 * x = 2

x/7 = 2

do cross multiplication

x = 14
