Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 108
Sample mean, = 107
Sample size, n = 110
Alpha, α = 0.02
Population standard deviation, σ = 7
Formula:
Putting all the values, we have
The test statistic is -1.50
You need to implement the process of "flip-flop" and multiply which is where you flip the second fraction and multiply.
÷
⇒×
Now you multiply across. 2×15=30 and 3×11=33
So now it is
-----------------------------------------------------------
To reduce to the lowest terms, find the GCF common factor
The GCF is 3
Divide both the numerator and denominator by 3
÷
=
