Step-by-step explanation:
Answer:
z-statistic
Step-by-step explanation:
We have to identify the correct test statistic to use with the given conditions.
- If the sample size is larger than 30, then the sample is considered to be large.
- We are given a sample size of 51, which is a a large sample.
- Also, the population standard deviation is known.
- Thus, we use the z-statistic when testing a hypothesis about a single mean.
- Formula:
where 
is the sample mean, 
is the population mean, 
is the population standard deviation and n is the sample size.

Answer:
Do you have a diagram to follow?
It will much help, and easier for answering.
It takes two steps to solve an equation or inequality that has more than one operation: Simplify using the inverse of addition or subtraction. Simplify further by using the inverse of multiplication or division. When solving an equation in general, we always keep in mind the notion that whatever we do to one side of the equation should also be done to the other side to ensure that the equation remains balanced.We know that we have completely solved a two-step equation if the variable, usually represented by a letter in an alphabet, is isolated on one side of the equation (either left or right) and the number is located on the opposite side. I hope this helps! :D
