A company pays an average of $14.00 per hour but the hourly salaries of everyone in the company are normally distributed. The standard deviation of the data is $0.75 per hour. Find the wages at the 2.5th percentile and 97.5th percentile.

a.97.5 th percentile : $16.25; 2.5 th percentile : $11.75
b.97.5 th percentile : $14.75; 2.5 th percentile : $13.25
c.97.5 th percentile : $15.50; 2.5 th percentile : $12.50
d.97.5 th percentile : $15.50; 2.5 th percentile : $11.75

c.97.5 th percentile : $15.50; 2.5 th percentile : $12.50

Step-by-step explanation:

Since the hourly salaries of everyone in the company are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = hourly salaries

µ = mean salary

σ = standard deviation

From the information given,

µ = $14

σ = $0.75

Looking at the normal distribution table, the z score corresponding to the 2.5 th percentile(0.025) is - 1.96

- 1.96 = (x - 14)/0.75

x - 14 = 0.75 × - 1.96 = - 1.47

x = - 1.47 + 14

x = $12.53

Approximately, x = $12.5

Looking at the normal distribution table, the z score corresponding to the 97.5 th percentile(0.975) is 1.96

1.96 = (x - 14)/0.75

x - 14 = 0.75 × 1.96 = 1.47

x = 1.47 + 14

x = $15.47

Approximately, x = $15.5

yes because a quadrilateral is equal to 4 sides and a rhombus has 4 sides so technacly it is a quadrilateral.
