You would distribute -4(3 - 5x) into looking like:
-12 +20x
This gives you
-12 + 20x ≥ -6x + 9
19,810 rounded to the nearest hundred is 19,800.
8 is in the hundreds place, and the number 1 is in front of it.
Numbers 1-4 in front of the number make the number stay the same.
Numbers 5-9 in front of the number make the numbers round up one number.
Answer:
Set of hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 20.5 oz
Sample mean,
= 20.4 oz
Sample size, n = 50
Population standard deviation, σ = 2.25 oz
First, we design the null and the alternate hypothesis
We use One-tailed z test(left tailed) to perform this hypothesis.
Formula:
Putting all the values, we have
Based on the significance level, we can make our decision and complete the hypothesis testing.
We may accept the null hypothesis or fail to accept depending on different significance level.
