B. What are the conditions required to use this test? Have the conditions been satisfied? Explain.

Answers

We use a chi-square test of homogeneity, as we have a single categorical variable measured within two different populations.

The requirements for this test are that we have two simple random samples (this is clearly satisfied, given that we are sampling all students who take the class that year) and that the expected value for each cell, defined as the cell's row sum multiplied by the column sum divided by the sum of all values in the dataset, is greater than 5. This is satisfied simply by testing for each value in the table.

Round 529 to two significant figures

Answers

With the number 529, the 5 is the most significant digit, because it tells us that the number is 500 and something. The 2 is the next most significent digit. After that digit is 9, so we will round it and add 1 onto 2 ( 2 + 1 = 3 ). Finally, 529 to 2 significant figures is: 530 ( and the second significant digit (3) has the overline ).
