An engineer wants to know if the average amount of energy used in his factory per day has changed since last year. The factory u

m_a_m_a [10]

Answer:

The calculated value Z = 1.8823 <1.96 at 0.05 level of significance

The average amount of energy used in his factory per day has changed since last year.

Step-by-step explanation:

Step(i):-

Given that mean of the Population = 2000 (MWH)

Given that size of the sample 'n' = 400

Given that mean of sample x⁻ = 2040 MWH

Given that the standard deviation = 425 MWH per day

Step(ii):-

Null hypothesis:H₀: μ = 2000 (MWH)

Alternative Hypothesis:H₁: μ≠ 2000( MWH)

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{2040-2000}{\frac{425}{\sqrt{400} } }$

Z = 1.8823

The calculated value Z = 1.8823 <1.96 at 0.05 level of significance

Final answer:-

The calculated value Z = 1.8823 <1.96 at 0.05 level of significance

The average amount of energy used in his factory per day has changed since last year.

What is mKNL? Enter your answer in the box.

sergejj [24]

Answer:

102°

Step-by-step explanation:

As the vertically opposite angles are equal,

$5x+2={3(x+14)$

Now let's solve for x now

$5x+2=3(x+14)\\$

$5x+2=3x+42$

$5x-3x=42-2$

$2x=40$

$\frac{2x}{2} =\frac{40}{2}$

$x=20 \\$

Now let's find the value of KNL

$3(x+14)\\3(20+14)\\3*34\\102$

Hope this helps you.

Let me know if you have any other questions ;-)
