Step-by-step explanation:
In triangle ABC,
The addition property of equality states that if the same amount is added to both sides of an equation, then the equality is still true.
Use addition property of equality, add 1 to both sides of previouse equality:
Answer:
The z-score (value of z) for an income of $1,100 is 1.
Step-by-step explanation:
We are given that the mean of a normally distributed group of weekly incomes of a large group of executives is $1,000 and the standard deviation is $100.
<em>Let X = group of weekly incomes of a large group of executives</em>
So, X ~ N()
The z-score probability distribution for a normal distribution is given by;
Z = ~ N(0,1)
where, = mean income = $1,000
= standard deviation = $100
The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Now, we are given an income of $1,100 for which we have to find the z-score (value of z);
So, <em><u>z-score</u></em> is given by = =
= 1
<em>Hence, the z-score (value of z) for an income of $1,100 is 1.</em>
