Answer:
And we can use the complement rule and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the bank account balances of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution of X is normal then the distribution for the sample mean is given by:
And we can use the z score formula given by:
And using this formula we got:
And we can use the complement rule and we got:

</span><span>9 x (t-6) = 3 x t t=4 et x=0 vraie
</span><span>4 x (t - 1) = t x t t=2 st x=0 vraie
