Step-by-step explanation:

Corresponding egg production before and after the light was put on form matched pairs.

The data for the test are the differences between the egg production before and after the light was put on.

μd = egg production before the light was put on minus egg production after the light was put on.

Before after diff

4 6 - 2

3 5 - 2

8 9 - 1

7 7 0

6 4 2

4 5 - 1

9 10 - 1

7 6 - 1

6 9 - 3

5 6 - 1

Sample mean, xd

= (- 2 - 2 - 1 + 0 + 2 - 1 - 1 - 1 - 3 - 1)/10 =

- 1

xd = - 1

Standard deviation = √(summation(x - mean)²/n

n = 10

Summation(x - mean)² = (- 2 + 1)^2 + (- 2 + 1)^2 + (- 1 + 1)^2 + (0 + 1)^2 + (2 + 1)^2 + (- 1 + 1)^2 + (- 1 + 1)^2 + (- 1 + 1)^2 + (- 3 + 1)^2 + (- 1 + 1)^2 = 16

Standard deviation = √(16/10

sd = 1.26

For the null hypothesis

H0: μd ≥ 0

For the alternative hypothesis

H1: μd < 0

The distribution is a students t. Therefore, degree of freedom, df = n - 1 = 10 - 1 = 9

The formula for determining the test statistic is

t = (xd - μd)/(sd/√n)

t = (- 1 - 0)/(1.26/√10)

t = - 2.51

We would determine the probability value by using the t test calculator.

p = 0.017

Since alpha, 0.05 > than the p value, 0.017, then we would reject the null hypothesis. Therefore, at 5% level of significance, it cannot be concluded that the increased light time increased egg production.

This technique would be adopted because it would lower production costs and increase economic profit.

Explanation:

Consider the given problem here there are “4 factors” of production these are “Land”, “labor”, “capital” and “entrepreneurial ability”. Now, price of each input is given in the question.

given the price and the cost adopting “technique 1” is given by.

=> C1 = 4*2 + 3*1 + 3*5 + 2*3

         = 32

Similarly, given the price and the cost adopting “technique 2” is given by.

=> C2 = 4*4 + 3*2 + 3*2 + 2*1

          = 30  

Similarly, given the price and the cost adopting “technique 3” is given by.

=> C3 = 4*2 + 3*4 + 3*3 + 2*1

          = 31  

Now, given the price and the cost adopting “technique 4” is given by.

=> C4 = 4*4 + 3*1 + 3*1 + 2*4

          = 30

Finally, given the price and the cost adopting “technique 5” is given by.

=> C5 = 4*4 + 3*3 + 3*2 + 2*1

         = 33  

here the most efficient technique is “2 and 4” having least cost.

Now, for new technology the cost of using it is given by.

=> 4*3 + 3*3 + 3*1 + 2*2 = 28 < 30

Therefore, This technique would be adopted because it would lower production costs and increase economic profit.

so, converting firstly the mixed fractions to improper fractions and then "adding".
