Answer:
x ≥ -2
Step-by-step explanation:
4x ≥ -8
Since we are solving for x, we are trying to get x alone on one side of the equation. We can easily do this by dividing by 4 on both sides.
4x ≥ -8
4x/4 ≥ -8/4
4x/4 = x and -8/4 = -2
x ≥ -2
Answer:
Dante most likely asked the students if they should change the school mascot. This is a statistical question because the question can be answered by data that varies.
Step-by-step explanation:
You can see that the results for this question are either "yes" or "no". This means that Dante asked a question with a yes or no answer related to changing the mascot. This question was probably something along the lines of whether or not the mascot should be changed.
The definition of a statistical question is "a question that should have different answers". Therefore, this is a statistical question because the answers will be different from student to student.
Hope this helps!
Answer:
z test statistic
Step-by-step explanation:
Given : In a hypothesis test, the claim is μ ≤ 25 while the sample of 34 has a mean of 21 and a population standard deviation of 5.9 from a normally distributed data set.
To Find : In this hypothesis test, would a z test statistic be used or a t test statistic and why?
Solution:
Claim : μ ≤ 25
Sample size = n = 34
Population Standard Deviation = 5.9
Since n > 30 and we are given the standard deviation of population .
So, we will use z test statistics .
Hence In this hypothesis test, z test statistic would be used.
