Answer:

The calculated value of t= -1.118860 does not lie in the critical region t= -1.714 or t= -2.5. Therefore we accept our null hypothesis that the mean score for Group 1 is significantly lower than the mean score for Group 2 for both significance level of 0.05 and 0.01

Step-by-step explanation:

Groups               Sample Size      Mean        Standard Deviation

1                              11                      65                   4.7

2                            16                      74                    2.5

Formulate null and alternate hypotheses as

H0 : u1 < u2 against Ha: u1 ≥ u 2

That is the mean of the group 1 is lower than the mean of the group 2

Degrees of freedom is calculated df = υ= n1+n2- 2= 11+16-2= 23

The significance level alpha is chosen to be ∝ = 0.05

The critical region t ≤ -t (0.05, 23) = -1.714

And if we choose alpha = 0.01 the critical region would be  

t ≤ -t (0.05, 23) = -2.5

Here the difference between the sample means is x`1- x`2= 65-74= -9

The pooled estimate for the common variance σ² is

Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]

= 1/11+16-2 [ (65)²+(74)²]

= 1/23[ 4225+5476]

= 1/23[9701]

=421.782

Sp =√ 421.782=20.5373

The test statistic is

t = (x`1- x` ) /. Sp √1/n1 + 1/n2

t= -9/ 20.5373√1/11+ 1/16

t= -9/8.0439

t= -1.118860

The calculated value of t= -1.118860 does not lie in the critical region t= -1.714 or t= -2.5. Therefore we accept our null hypothesis that the mean score for Group 1 is significantly lower than the mean score for Group 2 for both significance level of 0.05 and 0.01

Step-by-step explanation:

Answer:

Q'(0, -1)

R'(2, 5)

S'(-1, 0)

T'(-2, 9)

Step-by-step explanation:

Rule defined by [tex]T_{(-1,2)}.R_{\text{x-axis}}[/tex]

Step 1). Reflection of the figure about x-axis

(x, y) → (x, -y)

Step 2). Followed by the translation of 1 unit to the left and 2 units up  

(x, y) → (x - 1, y + 2)

Transformation of QRST by this rule,

Step 1.

Q(1, 3) → Q"(1, -3)

R(3, -3) → R"(3, 3)

S(0, 2) → S"(0, -2)

T(-2, 1) → T"(-2, -1)

Step 2.

Q"(1, -3) → Q'(0, -1)

R"(3, 3) → R'(2, 5)

S"(0, -2) → S'(-1, 0)

T"(-1, -1) → T'(-2, 9)

Answer:

yes, it's a circle

Answer:

The answer and explanation is on the picture.

Answer:

X = 11

Step-by-step explanation:

(13 + 17 + 15 + 20 + 14 + x) ÷ 6 = 15

13 + 17 + 15 + 20 + 14 + x = 15 x 6

13 + 17 + 15 + 20 + 14 + x = 90

13 + 17 + 15 + 20 + 14 = 79

79 + x = 90

90 - 79 = 11

X = 11

The right angle is 90 degrees.

The 3 inside angles are a total of 180 degrees.

The two acute angles would need to equal 180-90 = 90 degrees.

Using the ratio you have 3x + 7x = 90

Simplify to get 10x = 90

Divide both sides by 10 to get x = 9

Now you have the two angles:

Angle 1 = 3 x 9 = 27

Angle 2 = 7 x 9 = 63

Step-by-step explanation:2=120 1.5=90

Answer: 6.4 ounces per serving

Step-by-step explanation:

128 oz = 20 servings

Divide both sides by 20.

128 / 20 = 6.4

Answer:

A

Step-by-step explanation:

Find the mean:

Day 1: 2

Day 2: 1

Day 3: 4

Day 4: 5

Day 5: 0

Day 6: 7

Mean = [tex] \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17 [/tex]

This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.

Therefore we can conclude that:

"Chawrdi complied with the guideline because the mean number of hours played is [tex] \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17 [/tex].

Answer: 9

Step-by-step explanation:

The area of the obtuse triangle given is,

⇒ Area of triangle = 9 square units

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The obtuse triangle given below.

Here, Base = 9

And, Height = 2

Now, WE know that;

⇒ Area of triangle = 1/2 × Height × Base

Put all the values we get;

⇒ Area of triangle = 1/2 × Height × Base

⇒ Area of triangle = 1/2 × 2 × 9

⇒ Area of triangle = 9 square units

Thus, The area of the obtuse triangle given is,

⇒ Area of triangle = 9 square units
