Use the following diagram. Assume that the horizontal lines in the diagramrepresent duration of illness in 8 different people, out of a community of 700.• Three people became ill in June. Of them, two recovered in July and one inAugust. Five additional persons became ill in July; two of them recovered thatmonth and three recovered in August

The researchers followed 3 participants in a 5 year study. Begin by calculating the person-time for each participant. Then, calculate the total person-time by adding up the three individual person-times. If you find it helpful, you might want to create a graph to help visualize this information. What is the total person-time in this study?Participant 1: Year 1: follow-up, Year 2: lost to follow-up at the end of the yearParticipant 2: Year 1: follow-up, Year 2: follow-up, Year 3: follow-up, Year 4: disease at the end of the yearParticipant 3: Year 1: no observation, Year 2: follow-up, Year 3: follow-up, Year 4: follow-up, Year 5: death at the end of the year10 years 8 years 7 years 15 years

Think back to the example study earlier in this lecture. The researchers followed 3 participants in a 5 year study. You have already calculated the total person-time and found out that it is 10 years. During the study, there was one case of the disease. Calculate the rate. 101.13.33

Prepare a scatter diagram for each of the following pairs of variables and then express in words the apparent relationship between the two variables. Put the first variable on the horizontal axis and the second variable on the vertical axis.                                a.

Fill in the blanks. Round answers to the nearest WHOLE number.Suppose that an outbreak of cholera follows severe flooding in an isolated town of 7494 people. Initially (Day 0), 92 people are infected. Every day after, 11% of those still healthy fall ill. A. At the beginning of the first day (Day 1), how many people are still healthy? B. How many will fall ill during the first day? C. What is the total number of people infected after the first day?

Help the doctorSabarish, A doctor forms a grid where each cell represents the condition of a patient. The cell can take any of the three values as follows:              1-The person is virus free              2-The person is infected with the virus               3-Empty cellIt takes one day for the virus to spread from one person to another. Every day any virus free person who is adjacent (4-directionally) to the infected person catches the disease.Given the initial grid help the doctor to find the minimum number of days that must elapse until everyone has been infected. If this impossible return -1.Example:-Suppose the input grid is 2 1 1                                             1 1 3                                            3 1 1After day 1 the grid will be    2 2 1                                                  2 1 3                                                  3 1 1After day 2 the grid  will be  2 2 2                                                 2 2 3                                                 3 1 1 After day 3 the grid will be 2 2 2                                               2 2 3                                               3 2 1After day 4 the grid will be 2 2 2                                               2 2 3                                               3 2 2So, the minimum number of days is 4Input format:-Numbers of row in the gridNumbers of column in the gridContents of the grid(next row*column lines)Output format:-Minimum number of days required
