The number of deaths of children ages 1 to 14 in 1985 compared to 1991 for 10 states was gathered. (10 points) State Number of Child Deaths in 1985 Number of Child Deaths in 1991 1 33 51 2 53 33 3 58 51 4 73 44 5 88 89 6 130 142 7 212 195 8 213 215 9 275 269 10 313 312 Part A: Determine and interpret the LSRL. (3 points) Part B: Predict the number of child deaths in 1991 for State 11 if the number in 1985 was 65. Show your work. (3 points) Part C: Calculate and interpret the residual for State 11 if the observed number of deaths in 1991 was 42. Show your work. (4 points)

Solution :

From the output of regression equation given by

Number of death of children in 1991 =

Now, number of death of children in the year 1991 =

For x = no. of deaths of children in the year 1985 = 65

So substituting in the regression equation,

No. of deaths of children in year 1991 =  

                                                              =

                                                              ≈ 60

Now residual =

                      =

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
