Regarding the context regarding the coronavirus pandemic, see the table below, which refers to 5 groups of people infected with the coronavirus and the number of deaths in each group.

a) Tiago, another person who observes the table, has a clinical look and makes the following statement for the fifth class of the table. "With certainty, 7 deaths occurred in a group with a number of infected greater than or equal to 80 and being less than or equal to 89 infected people." When you analyze this statement that James made, do you agree or disagree? Justify your choice.

b) Tiago, wanting to be more precise, decides to calculate the average number of deaths among all groups of infected people presented in the table. When making this calculation, James will arrive at what value? And what will be the correct interpretation that James will make with the value obtained by the average? Present the calculation to obtain the mean and interpret the result.
