Answer:
Percent error = 4.29%
Step-by-step explanation:
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
Given the following data;
Experimental value = 67
Theoretical value = 70
Substituting into the equation, we have;
Percent error = 4.29%
Answer:
The proportion of individuals score at most 74 points on this test is 70%.
Step-by-step explanation:
The complete question is:
Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.
Solution:
Let <em>X</em> represent the scores on a reading ability test.
It is provided that .
Compute the probability that an individuals score is at most 74 points on this test as follows:
Thus, the proportion of individuals score at most 74 points on this test is 70%.
So we know that it's already 5 seconds behind on the first day.
On the second day, it's 6 seconds behind.
And on the third, it's 7 seconds behind.
And so on...
The difference between the day, and the seconds is 4.
This means, that whatever day it is (say 17 for example), and add 4, will come to how many seconds behind (17 + 4 = 21 in this case)!
So we subtract 29 by 4, to find the day:
29 - 4 = 25 days.
