Answer:
-The mean will decrease, and the median will stay the same.
Step-by-step explanation:
Before the point was added, the median was 45. The middle point is the 7th point The 7th point was 45. Now there are 14 points. We add the 7th and 8th points together and divide by 2 (Remember to place a point at 15) (45+45) /2 The median stays at 45
Choice A is the only answer in which the median stays the same
X - 89 = 7
Difference is - and is means equal to therefore is x - 89 = 7
Answer:
34% of scores should fall between your score and the mean.
Step-by-step explanation:
Let <em>X</em> denote the score.
It is provided that X follows a normal distribution with mean 110 and standard deviation 15.
A students score, <em>x</em> = 95.
Compute the probability of scores that should fall between the student's score and the mean as follows:
Thus, 34% of scores should fall between your score and the mean.
Answer:
313/7
Step-by-step explanation:
Here, we are interested in turning the wordings of the statement to numeric values.
We take it one at a time.
Sum of 35 and 1/5(35) = 35 + 7 = 42
This is added to 1/7(11 + 8)
= 1/7(19) = 19/7
So we have;
42 + 19/7 = (294 + 19)/7 = 313/7
