Data
The file: Birthweights.xlsx contains data on the following variables for a sample of 1000 births recorded in a large local hospital in 2015:
Variable
Description
Birthweight
Birthweight in grams
Gestation
Length of pregnancy in days
Smoke
Whether the mother is a smoker or not
Pre-pregnancy weight
Mother’s pre-pregnancy weight in kilograms
Height
Mothers height in centimetres
Status
Mother’s indigenous status
Age
Mother’s age in years
Background
Management at the hospital is interested in being able to better manage room allocations and bookings in their maternity ward. They are keen to identify mothers at risk of having low birth weight babies who may require additional hospital resources during their stay in the hospital.
The hospital has collected data for a number of previous births at the hospital. The data contains information on the variables outlined in the table above. As a consultant, they have approached you and asked if you could analyse this dataset.
Tasks
Part 1 - Analysis (80%)
1. Past records (2004) show that the average birthweight was 3500 grams. Test at 5% if the average birthweight in 2015 has increased with the improvement in general nutrition.
(Include all six steps for hypothesis testing.)
(2 marks)
2. Perform a two-sample t-test for each of the following tasks. (Include all six steps for hypothesis testing in each.)
(a) Determine if there is evidence that on average the weight of a baby of a mother who smokes is less than that of a mother who does not. (a = 5%)
(2 marks)
(b) Determine if being indigenous is a disadvantage in terms of birthweight. (a = 5%)
(2 marks)
The hospital management is particularly interested in whether you can develop a regression model to help them to predict the birthweight of a baby based on the variables in the data supplied. The model could then be used to predict birthweight to identify babies at risk in future.
By using the forward stepwise method, develop a multiple regression model to predict the birthweight.
Step 1: Gestation only
Step 2: Gestation and Smoke
Step 3: Gestation, Smoke and Pre-pregnancy Weight
Step 4: Gestation, Smoke, Pre-pregnancy Weight and Height
Step 5: Gestation, Smoke, Pre-pregnancy Weight, Height and Status
Step 6: Gestation, Smoke, Pre-pregnancy Weight, Height, Status and Age
Interpret the regression coefficients of all six (6) independent variables in the model obtained in Step 6, and comment on the statistical significance of each.
(3 marks)
Use Excel to obtain the correlation matrix for the following variables: Gestation, Pre-pregnancy Weight, Height, Age and Birthweight. Do you think multi-collinearity is a problem in the regression model? Are the correlation coefficients consistent with the regression coefficients obtained in the model in Step 6? Discuss briefly.
(3 marks)
Focusing on Steps 3 and 4, discuss fully how the introduction of Height in Step 4 affects the regression coefficient of Pre-pregnancy Weight.

4. Compute the difference in the average birthweight of babies of indigenous and non-indigenous mothers (called the birthweight difference, for simplicity). Discuss fully if there is any discrepancy between the regression coefficient of Status obtained in the regression model and the birthweight difference.

Part 2 – Report (20%)
You are required to submit a concise report (word limit: 400) presenting any important features or relationships in the data. The content of your report should be based on, but not restricted to, insights gleaned from your analyses conducted in Part 1.

Notes:
Part 1 - Analysis
For presentation and ease of marking, it is advisable to include relevant Excel output in your answer to each question in this part instead of placing them in appendices.
There is no word limit in Part 1.
Part 2 - Report
The report is primarily based on the data provided. If, however, you wish to include, and refer to, additional information, you can use any referencing system as long as it is used consistently.
You can include relevant charts and Excel objects in your report.
Use 1 & ½ spacing and font size of 11.
The word limit of 400 (with a tolerance of 10%) is exclusive of words in tables, appendices and reference list (if any).

Explanation / Answer
We shall analyse this using the open source statisitcal package R . the complete R snippet is as follows
# read the data into R dataframe
data.df<- read.csv("C:\Users\586645\Downloads\Chegg\birthweight.csv",header=TRUE)
str(data.df)
## question 1
## perform the t test
t.test(data.df$Birthweight,mu=3500,alternative = "greater" ,conf.level = 0.95)
## question 2
# a )
attach(data.df)
s <- data.df[ which(Smoke=='yes'),]
ns <- data.df[ which(Smoke=='no'),]
t.test(s$Birthweight,ns$Birthweight,alternative = "less")
## b)
attach(data.df)
ind <- data.df[ which(Status=='indigenous'),]
nonind <- data.df[ which(Status=='non-indigenous'),]
t.test(ind$Birthweight,nonind$Birthweight)
## regression model
data.df<-data.df[,-1]
mod <- lm(Birthweight~.,data=data.df)
summary(mod)
step(mod, direction='backward', trace = TRUE)
## correlation matrix
data.df<- data.df[,-c(2,5)]
cor(data.df)

The results are
t.test(data.df$Birthweight,mu=3500,alternative = "greater" ,conf.level = 0.95)
One Sample t-test
data: data.df$Birthweight
t = 2.3538, df = 999, p-value = 0.009387 ## as the p value is less than 0.05 , hence we can conclude that there is an increase in the average birthweight in 2015
alternative hypothesis: true mean is greater than 3500
95 percent confidence interval:
3512.14 Inf
sample estimates:
mean of x

t.test(s$Birthweight,ns$Birthweight,alternative = "less")
Welch Two Sample t-test
data: s$Birthweight and ns$Birthweight
t = -8.0074, df = 823.99, p-value = 1.991e-15 ## as the p value is less than 0.05 , hence we can conclude that the avergae birhtweight is less for mothers who smoke
alternative hypothesis: true difference in means is less than 0
95 percent confidence interval:
-Inf -217.3996
sample estimates:
mean of x mean of y

Welch Two Sample t-test
data: ind$Birthweight and nonind$Birthweight
t = -3.7421, df = 53.359, p-value = 0.0004478 # as the p value is less than 0.05 , hence we say that the results are significant and there is a disdvantage for being indigenious as the birth weight is less
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
-488.8571 -147.7155
sample estimates:

each coefficient can be interpreted as
for a unit change in the value of independent variable , the dependent variable changes by the coefficient value.
ex , for a unit change in the value of height , the birthweight changes by 15.10 units.

as we observe that none of the correlation values are high enough , we can conclude that the mulitcollinearlity is not a problem for the regression model.
