Many fast-food restaurants have soft drink dispensers with preset amounts, so that when the operator merely pushes a button for
antiseptic1488 [7]

Answer:

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

The Rank for  Group1  is 115.5 and Group 2 is 55.5.

Conclusion is that Worker productivity is higher with automatic dispensers.

Step-by-step explanation:

The null and alternative hypotheses are

H0: Group1 ≤ Group2   against the claim

Ha: Group1 > Group2

Alternative hypothesis is that Worker productivity is higher with automatic dispensers.

Calculations:

                                        Group1               Group2

Sample Mean   x `       139.22               114.67

Sample size n                   9                         9

Sample SD                     18.21                  11.937

Rank                               115.5                       55.5

U                                      10.5                          70.5

<u><em>The Rank for  Group1  is 115.5 and Group 2 is 55.5.</em></u>

<u><em></em></u>

<em><u>1. H0 hypothesis</u></em>

As p-value < alpha  and Z lies in the critical region, H0 is rejected.

The randomly selected value of Group1's population is considered have greater productivity  than the randomly selected value of Group2's population.

<em><u>2. P-value</u></em>

The p-value equals 0.0046.

<em><u>3. Test statistics</u></em>

<em><u>Z= u-μ+c/σ</u></em>

The critical region for one tailed test for z at 0.01 significance level is

z > 2.33.

The test statistic Z equals 2.6063, which lies in the critical region of acceptance z> 2.326

<u><em>4. Conclusion</em></u>

As the calculated test statistic lies in the critical region H0 is rejected and it is concluded that

<em><u>Worker productivity is higher with automatic dispensers. </u></em>

An adult brain is about 140 mm wide and divided into two sections (called "hemispheres" although the brain is not truly spherica
Sedbober [7]

Answer: 3.61×10^5 A

Step-by-step explanation: Since the brain has been modeled as a current carrying loop, we use the formulae for the magnetic field on a current carrying loop to get the current on the hemisphere of the brain.

The formulae is given below as

B = u×Ia²/2(x²+a²)^3/2

Where B = strength of magnetic field on the axis of a circular loop = 4.15T

u = permeability of free space = 1.256×10^-6 mkg/s²A²

I = current on loop =?

a = radius of loop.

Radius of loop is gotten as shown... Radius = diameter /2, but diameter = 65mm hence radius = 32.5mm = 32.5×10^-3 m = 3.25×10^-2m

x = distance of the sensor away from center of loop = 2.10 cm = 0.021m

By substituting the parameters into the formulae, we have that

4.15 = 1.256×10^-6 × I × (3.25×10^-2)²/2{(0.021²) + (3.25×10^-2)²}^3/2

4.15 = 13.2665 × 10^-10 × I/ 2( 0.00149725)^3/2

4.15 = 1.32665 ×10^-9 × I / 2( 0.000058)

4.15 × 2( 0.000058) = 1.32665 ×10^-9 × I

I = 4.15 × 2( 0.000058)/ 1.32665 ×10^-9

I = 4.80×10^-4 / 1.32665 ×10^-9

I = 3.61×10^5 A

Given f (x) = 3 x minus 1 and g (x) = 2 x minus 3, for which value of x does g (x) = f (2)?
antoniya [11.8K]

Answer:

X = there and halve

3(1/2)

Step-by-step explanation:

F(x) =3x -2

g(x )= 2x-3

F(2) = 3(2) - 2

= 6-2

= 4

So the value of x that can make g(x) = 4

4= 2x-3

7 = 2x

X= 7/2

X = 3 1/2
