The sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0, the results tend to
<h3>How to interpret Garret studies?</h3>
From the question, we have the following highlights
- The sample size is large enough
- The sample is at random
- Students who have a grade point average of 3.0 - 4.0 sleep for an average of 6.8 hours
- Students who have a grade point average of 2.0–3.0 sleep for an average of 6.4 hours
- There are no outliers
From the above highlights, the sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0
This is because 6.8 is greater than 6.4
This means that Garret's theory about the hours of sleep is correct

Step-by-step explanation:
117+114= 231
360-231= 129
Now find two numbers that add up to 129
Answer:
Step-by-step explanation:
It's a 30-60-90 triangle. The sides of a 30-60-90 triangle are in the ratio 1:√3:2
The side opposite the 90° angle is 12√3, so the side opposite the 30° is (12√3)/2 = 6√3.
The side opposite the 60° angle is (6√3)√3 = 18
x = 18
y = 6√3
Answer:
0.6069
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 69.3 ; Standard deviation = 2.58
For :
P(x < 70)
Z = (70 - 69.3) / 2.58
Z = 0.7 / 2.58
Z = 0.2713
P(Z < 0.2713) = 0.6069
10 + 6n = n - 5
can you solve that?
