Was there discrimination on the Titanic? Were first-class passengers given greater
access to life boats?
The unsinkable liner Titanic collided with an iceberg on her maiden voyage
in 1912 and sank with great loss of life. On board were 1317 passengers, some of
whom had paid a very much higher fare than others for the voyage. A not very
subtle sub-text in the most recent Titanic movie was the notion that the first class
passengers survived at a higher rate than other passengers.
Imagine we can regard the first class passengers as a sample of the total population
on board at the time of the collision. There were 324 first class passengers of whom
62% survived the sinking. In other words our sample proportion p^ = 0:62 while n is
324. The proportion of survivors from the total population (all passengers) on board
was p = 0:38:
Using a 0.05 significance level, test whether the survival rate for first class passengers
was greater than that for all passengers. Do the six steps of the test.

Expert Solution

Solution: Here concept of significance of single proportion is used.

Question 2: “The RMS Titanic was an Olympic-class passenger liner, launched for the first time in 31 May 1911. The ship’s steel was “probably the best plain carbon ship plate of the time”. Nevertheless, shortly before midnight on 14 April 1912, four days into the ship’s maiden voyage, Titanic hit an iceberg. The impact caused the hull to fracture and water poured into the ship, sinking it two hours and forty minutes later. Of the 2223 people on board, only...

Selected Rejected Blacks 26 22 Whites 206 53 In discrimination cases, sometimes the blacks and whites described in such a table are viewed as samples from theoretical populations that might result if large numbers of blacks and whites were considered for promotion by the agency. Test the claim that the population of whites selected for...

In my physics class, we are going over the Doppler Effect. We were given four different equations for two different scenarios: - When the observer is stationary but the source is moving - When the observer is moving but the source is stationary I was given a problem where both the observer AND the source are moving at some velocity. The source is emitting a given frequency while traveling at a given velocity. The observer is OBSERVING that frequency at...
