taurus [48]

Answer:

a) T test

b) Claim

because critical value is not equal to test statistic then reject null hypothesis

Step-by-step explanation:

Construction of hypothesis

H₀  : p = 75

H₁  : p  ≠ 75

Here Standard deviation = 7

sample = n = 50

Average = x-bar = 78

Level of significance:

∝ = 5% = 0.05

Degree of freedom:

df = n-1

  = 50 -1 = 49

Critical value :

± 1.96

a) T test

test t is  used as average X mean is used

Test Statistic:

t = X₂ - X₁ / Sd /√n

= 78 - 75 / 7/√50

=3.0304

Critical region :

We take two tail T test

test statistic is in reject interval. Reject H₀

b) Claim

because critical value is not equal to test statistic then reject null hypothesis

Naya [18.7K]

Answer: 4.25

Step-by-step explanation:

2(d-3) + 22d= 120-24

2d - 6 + 22d= 96

2d +22d= 96+6

24d= 102

d= 102/24

What is the area of this figure? <br><br> ___ units^2
enot [183]

Answer:

42\ units^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of two triangles

<u>Find the area of rectangle</u>

Observing the graph

The area of rectangle is equal to

A=bh=(2+5)(2+2)=28\ units^{2}

<u>Find the area of the top triangle</u>

A=\frac{1}{2}bh=\frac{1}{2}(2+5)(4-2)=7\ units^{2}

<u>Find the area of the bottom triangle</u>

A=\frac{1}{2}bh=\frac{1}{2}(2+5)(-2+4)=7\ units^{2}

the area of the figure is equal to

A=28\ units^{2}+7\ units^{2}+7\ units^{2}=42\ units^{2}
