It is believed that the median yearly income in a suburb of Atlanta is $70,000. A sample of 67 residents was taken. Thirty-eight had yearly incomes above $70,000, 26 had yearly incomes below $70,000, and 3 had yearly incomes equal to $70,000. The null hypothesis to be tested is $ H_0: \text{Median} = \$70,000 $.The mean and the standard deviation (respectively) for this test about the median are:- $ \bigcirc $ 32 & 16- $ \bigcirc $ 33.5 & 16- $ \bigcirc $ 32 & 4- $ \bigcirc $ 33.5 & 4 Sixteen people were given two types of cereal, Brand X and Brand Y.

It is believed that the median yearly income in a suburb of Atlanta is $70,000. A sample of 67 residents was taken. Thirty-eight had yearly incomes above $70,000, 26 had yearly incomes below $70,000, and 3 had yearly incomes equal to $70,000. The null hypothesis to be tested is $ H_0: \text{Median} = \$70,000 $.

The mean and the standard deviation (respectively) for this test about the median are:

- $ \bigcirc $ 32 & 16
- $ \bigcirc $ 33.5 & 16
- $ \bigcirc $ 32 & 4
- $ \bigcirc $ 33.5 & 4

$Sixteen people were given two types of cereal, Brand X and Brand Y. Two people preferred Brand X and thirteen people preferred Brand Y.
