Question

For the statement? below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify which represents the claim.

The standard deviation of the base price of a certain type of? all-terrain vehicle is at least ?$327.
Write the claim as a mathematical statement.
A. equals327
B. sigmagreater than327
C. sigmaless than or equals327
D. sigmanot equals327
E. sigmagreater than or equals327
F. sigmaless than327

Answer 1

Option E - sigma greater than or equal to $327

Explanation:

In this question, we are testing whether the standard deviation of the base price of a certain type of all-terrain vehicle is at least $327.

Now, standard deviation is denoted by the symbol sigma(σ). Since the test is saying it should be at least $327, it means it should either be equal to $327 or greater than $327.

Thus, we would use the symbol ≥ which means "greater than or equal to".

Thus, the claim as a mathematical statement would be;

sigma greater than or equal to $327
