Pulse rate. The distribution of the pulse rate in the CA population has the mean of 65 and the standard deviation of 8.
Assume that we have selected 36 individuals from CA population. Find the probability that their average pulse rate is above 67.
How your answer to a) will change if you select 64 individuals and you want to find the probability that their average pulse rate is above 67?
Will that be unusual to get that after selecting 36 individuals, their average pulse rate was found to be equal to 70? Explain.
