Question

ECG records how electric signals are transmitted throughout the heart and cons- ists of
waves called P, Q, R, S, T and U. Let's assume that the interval between Q and T waves in a
grown man, so called QT-interval, is normally distributed with the mean 400 ms and
standard deviation 20 ms.
If a grown man is picked random and his QT interval measured, what is the probability of
the interval being longer than 420 ms? b) 5% If a grown man is picked at random and his QT
interval measured, what is the probability of the interval being between 400 and 420 ms? c)
5% How long needs a QT interval to be, at mininum, in order to be among the 20 % longest
QT intervals in a grown man?
Allf a grown man is picked at random and his QT interval measured, what is the probability
of the interval being longer than 420 ms
b) If a grown man is picked at random and his QT interval measured, what is the probability
of the interval being between 400 than 420 ms
C.) how long needs a QT interval to be, at minumum in order to be among the 20% longest
QT intervals in a grown man?
