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
