Statistical analysis

Paper, Order, or Assignment Requirements

Data on health, economic livelihoods, food security, and Ebola vigilance from representative survey of Monrovia conducted from December 6, 2014 to January 7, 2015 by Parley, a Liberian NGO, were made public and available at https://data.hdx.rwlabs.org/dataset/data-for-ebola-recovery. The selection of respondents (1572) followed a three-stage sampling procedure. In the first stage, 77 communities were randomly selected from all of Monrovia’s fifteen administrative wards in proportion to their population size. In the second stage, twenty households were randomly selected within each community following a random-walk procedure. Within each household, a single adult respondent was randomly selected for the survey. The survey covered outreach efforts, attitudes toward survivors, knowledge of Ebola symptoms and transmission paths, uptake of Ebola prevention practices, Ebola incidence histories, health outcomes, food security, economic outcomes, and social outcomes.Data
The data for the analysis is stored in the dataset ebola_data_public_trimmed.xlsx. The survey itself with the names of the columns (where the answers are recorded) is given in ebola_survey_public.xlsx dataset. Select a sample of 100 observations (n = 100) from these data.

Data analysis and report
For each of the following studies (2-7) formulate the null and alternative hypotheses; choose, justify and perform an appropriate statistical test using MINITAB; provide all MINITAB outputs; write a brief 0.5 pages report and conclusions.

(1) For your unique dataset summarise information about your respondents and present graphically the frequency distributions of your respondents with respect to gender and age/age groups.
(2) Find out whether there is a significant difference in the knowledge about the average incubation time of Ebola between gender groups.
(3) Investigate whether there is a significant difference in number of males and females attending a public gathering like video clubs, entertainment centres, or other crowded areas.
(4) Show whether the proportion of people using hand sanitizer is different between age groups that you defined previously
(5) Explore whether there is any correlation between education status and the amount of money respondents earn in a normal week before Ebola outbreak. Note: do not use data with code88).
Independent research
(6) The probability that a patient recovers from Ebola is 0.3. Generate two random numbers between 0 and 150 using MINITAB and paste the outputs into your report. Denote by A the smallest number and by B the largest number out of these two generated numbers. If 150 people are known to have contracted this disease, calculate by hand the probability that between A and B survive.
(7) Think of a meaningful question and interrogate your data using an appropriate statistical test.
(8) Draft a 1 page non-technical letter to the World Health Organization (WHO) summarising your findings and their possible implications for WHO’s outreach activities
to fight Ebola.
