In a sample of 30 individuals of the total population living in a city, we got the following info about their incomes:
- People with no incomes : 1
- People getting 500 €/month: 2
- People getting 1000 €/month: 3
- People getting 1500 €/month: 5
- People getting 2000 €/month: 8

Ex. 1. Find the Arithmetic Mean (average) and the Geometric Mean
Ex. 2. Find the Median and the Mode
Ex. 3. Find the Deviation of each one of the values, and find the result of the total addition of them all
Ex. 4. Find the Variance and the Standard Deviation
Ex. 5. Draw a columns graph so that we can see the distribution of the above data according to the frequency
Ex. 6. According to that sample (let’s assume it is representative of the population and that it is a normal distribution), if you ask an individual randomly, what is the probability that he/she gets a monthly income between 1062€ and 2938€?
Ex. 7. According to that sample (let’s assume it is representative of the population and that it is a normal distribution), if you ask an individual randomly, what is the probability that he/she gets a monthly income lower than 1062€?
