Fiona recorded the mean math exam grade for six random samples of students from the entire seventh-grade class. Sample Sample Me
an Grade 1 65 2 92 3 78 4 45 5 95 6 70 Why is a valid prediction for the mean of the population not possible using these samples?
1 answer:
The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.
<h3>Why can't Fiona use the means she recorded?</h3><h3 />
Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.
In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.

Answer:
angle D is 90⁰
E is 66⁰
and F is 114⁰
No, the standard form is Ax + By = C. The form you have now is slope intercept form. So the correct way is 2x - y = 5.
