<span>If
your gross pay (pay before deductions) is $2,200.00 per month, and your take
home pay (amount of your pay check) is $1,421.00.
Question: What percent to the nearest tenth of your gross pay is deducted for
taxes and other items?
=> 2 200 dollars per month is the total number of gross.
=> 1 421 dollars the only amount you take home.
Let’s solve for the gross pay deducted.
=> 2 200 – 1 421 = 799 dollars
=> 799 dollars / 2 200 dollars = 0.35
=> 0.35 * 100% = 35%
Thus, 35% were deducted to his salary</span>
We have been given that a set of average city temperatures in May are normally distributed with a mean of 20.66°C and a standard deviation of 2 C. The average temperature of Singapore is 26°C. We are asked to find the proportion of average city temperatures that are lower than that of Singapore.
First of all, we will find z-score corresponding to sample score of 26.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we need to find probability of a z-score less than 2.67 that is .
Using normal distribution table, we will get:
Upon rounding to 4 decimal places, we will get:
Therefore, approximately of average city temperatures are lower than that of Singapore.
