A) Explain the difference between descriptive and inferential statistics.
B) What happens to the margin of error when the confidence level increases.
C) Discuss the relationship between sample size and margin of error.
Homework Answers
a)
Descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables.Inferential statistics makes inferences and predictions about a population based on a sample of data taken from the population in question.
b) When confidence level increases, margin of error increases.
c) As sample size increases, margin of error decreases.

What is the difference between descriptive and inferential statistics? Obviously only a crude (but accurate) answer is necessary. 16. 17. A researcher believes that the number of deaths per year to a very rare disease is a Poisson distribution. For the past five years, there have been 2, 5, 6, 5,4 deaths. Estimate the probability that exactly 2 people will die from this disease in the next year 18. Traditionally, I give one free question on a final. This is...

Statistics Grades: The statistics grades in the fall semester had mean of 65. The SRS were taken from different statistics groups (A, B, C and D) considering that the total number of students that took part on the exam was 110. Assuming that the change in the grades has a normal distribution with standard deviation σ= 10, We computed a 90% confidence interval of the mean change in score μ in the population of all statistics students. A) Find a...
