Answer:
a = 4
Step-by-step explanation:
Given equation:
4a - 5 = 11
Add 5 to both sides:
⇒ 4a - 5 + 5 = 11 + 5
⇒ 4a = 16
Divide both sides by 4:
⇒ 4a ÷ 4 = 16 ÷ 4 
⇒ a = 4

When the population mean and standard deviation are known, you use the standard normal distribution 
<h3>How to determine the distribution?</h3>
There are several probability distributions; these include
- Normal distribution
- Poisson distribution
- Chi square distribution
- Binomial distribution
- Etc
Of all these distribution, only the standard normal distribution can be used when the population mean and standard deviation are known,
Note that it is also referred to as the z-distribution
