Explanation / Answer

The data image file is not clear and it is generally prefered if they are given in csv or text format. Anyways, let us assume that the file is named "myglmdata.csv" with variable names as indicated in your image and description. Furthermore, we assume that the myglmdata.csv file is present in the current working directory. We then proceed with the R program as follows:

mydata <- read.csv("myglmdata.csv",header=TRUE)

mydata$NasalSpray <- as.factor(mydata$NasalSpray)

mydata$Vitamin <- as.factor(mydata$Vitamin)

mydata$Soy <- as.factor(mydata$Soy)

mydata$Fruit <- as.factor(mydata$Fruit)

mydata$Gender <- as.factor(mydata$Gender)

glm_fit <- glm(NumInf~NasalSpray+Vitamin+Age+Height+Weight+Soy+Fruit+Gender+Days,data=mydata,family=poisson())

summary(glm_fit)

This should give you most of your answers.
