Answer:

False

Step-by-step explanation:

From the question we are told that

The coefficient for the training is $r = 0.55$

The standard error is $SE = 1.06$

The confidence level is 95%

Generally the level of significant is mathematically represented as

$\alpha =( 100 -95)\%$

=> $\alpha = 0.05$

Generally the critical value of $\alpha = 0.05$ obtained from the normal distribution table is $Z_{0.05} = 1.645$

Generally the test statistics is mathematically represented as

$t = \frac{r }{SE}$

=> $t = \frac{0.55}{1.06}$

=> $t = 0.5189$

Generally given that the $t < Z_{\alpha }$

Hence there is no sufficient evidence to conclude that the program has a positive and statistically significant impact on wages at a 95% confidence level.

So the answer is False

A new car is purchased for $43,000 and over time its value depreciates by one half every 6 years. What is the value of the car 2

forsale [732]

Answer:

$1,567.62

Step-by-step explanation:

If the car depreciates 50% every 6 years, we can do the following:

$43,000 ÷ 2(year 6) = $21,500

$21,500 ÷ 2(year 12) = $10,750

$10,750 ÷ 2(year 18) = $5,375

$5,375 ÷ 2(year 24) = $2,687.5

Now, for us to know how much it depreciates in 5 years to reach 29 years:

50% = 0.5 = 1/2 ÷ 6years = 0.0833 annually * 5years = 0.4167

$2,687.5 * 0.4167 = $1,119.88

$2,687.5 - $1,119.88 = $1,567.62 is the value of the car 29 years after!
