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) You, student, by observing the data tabulated in the table above, come to what conclusion about the absolute frequency of the second grade? b) João, a person observing the table, calculates and states that the relative frequency of the fourth class is 48.46% and informs that 48.46% of the number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected. Do you agree with João's calculation and interpretation? If you agree or disagree, provide the calculation and interpretation that justifies your choice. c) Going deeper, Maria, another person who looks at the table, interprets that 16 deaths occurred in the group with a number greater than or equal to 40 and less than 70 infected people. When you see this interpretation that Maria made, do you agree or disagree? What is the name, statistically speaking, that is given to the calculation made by Maria to arrive at the information she made? Justify your answers
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) You, student, by observing the data tabulated in the table above, come to what conclusion about the absolute frequency of the second grade?
b) João, a person observing the table, calculates and states that the relative frequency of the fourth class is 48.46% and informs that 48.46% of the number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected. Do you agree with João's calculation and interpretation? If you agree or disagree, provide the calculation and interpretation that justifies your choice.
c) Going deeper, Maria, another person who looks at the table, interprets that 16 deaths occurred in the group with a number greater than or equal to 40 and less than 70 infected people. When you see this interpretation that Maria made, do you agree or disagree? What is the name, statistically speaking, that is given to the calculation made by Maria to arrive at the information she made? Justify your answers.
a) Absolute frequency of second grade that is 50-60 is 3.
b) Relative freq. = freq. of that group/(sum of frequencies)
For fourth group (70-80):
R.F. = 10/33 = 0.3030
30.30% number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected.
so, João's calculation is not correct we have 30.30% no. of deaths in that group not 48.46%.
