The confidence interval did give convincing evidence that there is difference in the population mean number of pairs of shoes for boys and girls at the school.

<h3>Why does the confidence interval did give convincing evidence?</h3>

The interval is one that gave a good convincing evidence, based on the fact that the number 0 stands as NO difference ( (girls boys) and thus it is = 0 ).

It is also not  not included in this interval and as such, it can mean that the difference in the mean number of shoes owned by girls and  the mean number of shoes owned by boys is 0 .

sukhopar [10]

a. U.S labor productivity in 2035 would be $206,800 per worker.

b.  U.S labor productivity in 2035 would be $68,100 per worker.

c. Labor productivity per worker in 2035 with the higher growth rate is 3.04

a. Calculation to determine  what the U.S labor productivity in 2035 would be $ per worker assuming productivity grows by 3.7 percent per year

Given:

Labor Productivity in 2015 = $100,000

Growth rate = 3.7%pa or  0.037

Using this formula

Future value = Present value*(1+Growth rate)^Number of years

Let plug in the formula

2035 labor productivity per worker=100,000(1 + 0.037)^20

2035 labor productivity per worker= $206,811.71

2035 labor productivity per worker= $206,800

( rounded to nearest $100)

b.Calculation to determine  what the U.S labor productivity in 2035 would be $ per worker assuming productivity falls to 1.9 percent per year

Given:

Labor Productivity in 2015 = $100,000

Growth rate = -1.9%pa or -0.019

Using this formula

Future value = Present value*(1+Growth rate)^Number of years

Let plug in the formula

2035 labor productivity per worker= 100,000(1-0.019)^20

2035 labor productivity per worker= $68,136.55

2035 labor productivity per worker= $ 68,100

( rounded to nearest $100)

c. Calculation to determine How much larger would labor productivity per worker be in 2035 with the higher growth rate

2035 labor productivity per worker=($206,811.711/$68,136.55121)

2035 labor productivity per worker= 3.04 times

Inconclusion:

a. U.S labor productivity in 2035 would be $206,800 per worker.

b.  U.S labor productivity in 2035 would be $68,100 per worker.

c. Labor productivity per worker in 2035 with the higher growth rate is 3.04
