Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

Data on the numbers of hospital admissions resulting from motor vehicle crashes are given below for Fridays on the
6th of a month and Fridays on the following 13th of the same month. Assume that the paired sample data is a simple
random sample and that the differences have a distribution that is approximately normal. Construct a 95% confidence
interval estimate of the mean of the population of differences between hospital admissions. Use the confidence
interval to test the claim that when the 13th day of a month falls on a Friday, the numbers of hospital admissions from
motor vehicle crashes are not affected.

In this example, µa is the mean value of the differences d for the population of all pairs of data, where each individual
difference d is defined as the number of hospital admissions on Friday the 6th minus the number of hospital
admissions on Friday the 13th. Find the 95% confidence interval.

Researchers from a certain country were interested in how characteristics of the spleen of residents in their tropical environment compare to those found elsewhere in the world. The researchers randomly sampled 91 males and 109 females in their country. The mean and standard deviation of the spleen lengths for the males were 10.9 cm and 0.9 cm, respectively, and those for the females were 9.8 cm and 1.1 cm, respectively.
