PLEASE TAKE NOTE THAT I NEED TO SEE THE WORKINGS AND NOT JUST THE ANSWERS

1.Looking over passenger data from the Titanic, you wish to determine whether a person's chance of survival was independent of whether they were an adult man, adult woman, or child. You have the following data regarding the number of passengers in each of those groups who survived and did not survive:

Women Children Men

Survived 304 56 128

Deceased 108 56 648

(a)Which statistical test does this scenario call for?

(b)Why that statistical test?

(c)State Ho. Be careful - use the correct language for this test

(d)State H1. Be careful - use the correct language for this test(

(e)Provide a table, similar to the one included in the question, that indicates the expected value for each cell.

(f)When calculating your ², you calculate a value for each cell in the table based on the observed and expected values for that cell. Make a table that contains the formula for each cell, using the correct observed and expected values for each cell. Hint: Make something like Table 18.4 in the text

(g)Calculate the value for your ²

(h)Calculate the Degrees of Freedom

(i)Please report your ² statistic using the proper formatting and degrees of freedom

(j)What is the critical F-score(s) for alpha = 0.05

(k)What is your p-value?

(l)What is the statistical decision regarding Ho?

(m) What is the substantive conclusion? Hint: Be certain that it doesn't sound like a statistical conclusion.

2.Looking over the same passenger data from the Titanic, you wish to determine whether a person's chance of survival was independent of booking class (first class, second class, or steerage). You have the following data regarding the number of passengers in each of those groups who survived and did not survive:

First Class Second Class Steerage

Survived 199 117 172

Deceased 120 155 537

(a)Which statistical test does this scenario call for?

(b)Why that statistical test?

(c)State Ho. Be careful - use the correct language for this test

(d)State H1. Be careful - use the correct language for this test

(e)Provide a table, similar to the one included in the question, that indicates the expected value for each cell.

(f)When calculating your ², you calculate a value for each cell in the table based on the observed and expected values for that cell. Make a table that contains the formula for each cell, using the correct observed and expected values for each cell. Hint: Make something like Table 18.4 in the text

(g) Calculate the value for your ²

(h)Calculate the Degrees of Freedom

(i)Please report your ² statistic using the proper formatting and degrees of freedom

(j) What is the critical F-score(s) for alpha = 0.05

(k)What is your p-value?

(l)What is the statistical decision regarding Ho?

(m)What is the substantive conclusion? Hint: Be certain that it doesn't sound like a statistical conclusion.

(g)Calculate the value for your ² (1 point)

(h)Calculate the Degrees of Freedom (1 point)

(i)Please report your ² statistic using the proper formatting and degrees of freedom (2 points)

(j)What is the critical F-score(s) for a = 0.05 (1 point)

(k)What is your p-value?(1 point)

(l)What is the statistical decision regarding H0? (1 point)

(m) What is the substantive conclusion? Hint: Be certain that it doesn't sound like a statistical conclusion. (1 point)
