Answer:
% error = 3.3%
Step-by-step explanation:
Percent Error Formula:
% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100
% error = ( (12.7 - 12.3) / 12.3 ) * 100
% error = (0.4/12.3) * 100
% error = (0.03252033) * 100
% error = 3.25203252
% error = 3.3%
Answer:
0.002
Step-by-step explanation:
We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.
Standard error of the mean = standard deviation/√n
Standard error of the mean = 32/√50 = 4.52
Now we can use this Standard error of the mean to estimate z as follows:
Z = (x – mean)/standard deviation
Z = (190-177)/4.52
Z = 2.87
Using a Z table we can find probability that mean is under 190
P (z<190)= 0.998
For the probability that the mean exceed 190 lbs we substract from 1
P(z>190) = 1 - 0.998 = 0.002
Answer:
Okay so 5th power of 2 Plus second power of 2 minus 3rd power of 3
