Question
Suppose a state has a Child death rate of 15. Predict the actual infant mortality rate for this state based on this model and include an appropriate 98% interval for this value.
![A study on the relationship between Infant mortality rate and the overall Child death rate in the 50 states in the U.S
was conducted. In the data, the sample variance of Child death rate is 225.538, while the average Infant mortality
rate is 7.126. The model output for this relationship fit in R is presented below.
