Answer:
And we can find this probability with this difference:
And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
Explanation:
For this case we can define the random variable X as "hours that a person watches television". For this case we don't have the distribution for X but we have the following parameters:
We can assume that the distribution for X is normal
And we want to find this probability:
And we can use the z score formula given by:
And we can find the z score for each limit and we got:
And we can find this probability with this difference:
And then we can conclude that the probability that someone watches between 3 and 5 hours a day is approximately 0.591 using a normal distribution
