First, you subtract 8 by both sides ( 8-8/ 20-8) so now your equation is 3n=12. Next, you multiply 3n by 3, and get 0, and 12 multiplied by 3 and the answer is 36! Hope this helped.
Answer:
0.13591 = 13.59%.
Step-by-step explanation:
We have been given that weekly wages at a certain factory are normally distributed with a mean of $400 and a standard deviation of $50.
First of all let us find the z-score for our given sample score using z-score formula.
, where,
,
,
,
.
Let us find z-score for sample score 500.
Let us find the probability of both z-score using normal distribution table.
Since we know that probability between two z-scores can be found by subtracting the smaller area from the larger area as:
Upon substituting our values we will get,
Therefore, the probability that a worker selected at random makes between $450 and $500 is 0.13591 or 13.59%.
