Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
<h3>168 in 2 and then 132 in 2</h3>
Answer:
x+3
Step-by-step explanation:
Answer:
so graph your first point. (x=2, y=1)
Step-by-step explanation:
Your 5/3 is your rise over run. So go up 5 from 2 you should be at 7 and over 3 from your 1 so your next point would be (x=7, y=4) now get a ruler and connect your two points. make sure to use a ruler to make your line straight.
I think that this is the resolution
2/3×5/-4 = 10/-12
hope this helps
