Hypothesis test of proportions On April 15th 1912, the R.M.S. Titanic sank into the north atlantic ocean resulting in th loss of more than 1500 passengers and crew. Below is a number of passengers and crew of survivors for the crew, first, second, and third class. Find the proportion of survivors by type of service crew, first, second and third. Test the hypothesis at the 99% confidence level that the proportion of first class survivors is the same as third class (25) What do you calculate for the test statistic: c? what is the critical sttistic?

Example: Independent t-Test ● A group of 30 people jump into the Atlantic. Their temperature is taken immediately when they get out of the water (mean = 96.3). At the same time, the temperatures of 30 random people waiting on the beach are also taken (mean = 98.4). Do the two groups significantly differ? ● a) What hypothesis test? ● b) Assumptions?
