The ID50 (Infective Dose) value is the concentration of pathogen
required to infect 50% of a population. (or a dose which is
required for a 50% chance of infection in a host).
Following is the graph to interpret ID50
From the graph the concentration of the infectious dose at which
50% of the population shows signs of infection can be infered to be
the ID50 Value.
This type of experiment is however not suitable for all type of
Pathogens and is majorly used for Viruses due to the uncertainty of
the viability/infectivity of bacteria.

a) I predict that the graph for light inensity as a function
of linear position will have high and low waves as the pattern is
scanned across the light sensor. How can I explain why this is
true?

Since residuals measure how far the observations are from the regression line, they are often used to assess the fit of the regression line to the data. We might display these vertical deviations graphically using a residual plot. By plotting the residuals against the explanatory variable x, we effectively magnify the deviations (that is, change the y-axis from response to vertical deviations), which allows for a better and closer examination of the deviations. Describe what a residual plot would look...

there is an experiment. Does diet affect blood pressure? All subjects go through all three treatments. First, they eat a diet with a lot of salt. Their blood pressure is measured. Second, they eat a diet with a lot of sugar. Their blood pressure is measured again. Third, they eat a diet with a lot of protein. Their blood pressure is measured a third time.
