So convert them all to percentages
Anna: 19%
Laura: 17/20 then times by 5 to get 85%
therefore she saves 15%
David: 2:8 = 2/10 saved = 20%
so david saves the most
Answer:
False
Step-by-step explanation:
From the question we are told that
The coefficient for the training is 
The standard error is 
The confidence level is 95%
Generally the level of significant is mathematically represented as

=> 
Generally the critical value of
obtained from the normal distribution table is 
Generally the test statistics is mathematically represented as

=> 
=> 
Generally given that the
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
Answer:
You would just divide $480 by 2 and get the answer of $240.
