Answer:

Explanation:

For example: Suppose you want to check the average working hour of employees. You may think that the average duration of an employees is 7.6 hours. You want to check this claim so you collect a sample of 20 employees and note their duration of work. (please check attached file for this, and continue)

NULL HYPOTHESIS H0:u= 7.6 HOURS

ALTERNATIVE HYPOTHESIS Ha: ≠7.6 HOURS

alpha=0.05

t= 7.765-7.6/1.25/sqrt(20)

t= 0.165/1.25/4.47

t= 0.165/0.28

t= 0.589

degrees of freedom= n-1=20-1=19

t critical = 2.09

Since t critical is GREATER than t calculated therefore we fail to reject null hypothesis H0.

From this we can conclude that We don't have enough or sufficient evidence to say that the mean working duration is different than 7.6 hours.

umka2103 [35]

Answer:

The Annual investment that you will to make will be $1,069.01

Explanation:

In order to calculate the uniform annual investment that will you have to make on the child's 8th through 17th birthdays to meet this goal, we have to make the following calculations:

First we need to calculate the Amount you have at the end of child's 8th year = 600*(1+0.05)^4 + 600*(1+0.05)^3 + 600*(1+0.05)^2 + 600*(1+0.05)^1 = $2,715.38

Therefore, Value of this amount at the end of 17th year = $2715.38 * (1+0.05)^9 = $4,212.45

So, Amount required to be saved = $16,000 - $4,212.45 = $11,787.55

Therefore, to calculate the annual investment we would have to use the following formula:

FV of annuity = P*[((1+r)^n - 1)/r]

P - Periodic payment =?

r - rate per period = 0.05

n - number of periods = 17-8 = 9

$11787.55 = P*(((1+0.05)^9 - 1)/0.05)

P = $11,787.55/11.03 = $1,069.01

The Annual investment that you will to make will be $1,069.01

Sophie is willing to sell her used economics textbook for $30. Ruby is willing to pay $60 for the used economics textbook. Sophi
erastovalidia [21]

Answer:

The correct answer is option A.

Explanation:

Sophie is willing to sell a textbook for $30, while Ruby is willing to purchase it for $60. Both negotiate and agree on a price of $45.

The gain for Sophie will be the difference between the minimum price she was expecting and the price she gets for the textbook.

Gain for Sophie

= $45 - $30

= $15

The gain for Ruby will be the difference between the maximum price she was willing to pay and the price she actually paid.

Gain for Ruby

= $60 - $45

= $15

So, both of them have a gain of $15 from trade.
