You have sample data that leads you to believe that the average high temperature in Oklahoma City is 92°F. What is the alternative hypothesis, Ha, for this situation?

B. µ > 90

Step-by-step explanation:

I can confirm that the answer to your question is B.

Given:

The equation of the ellipse is

The length of its major axis is 6.

To find:

The value of k.

Solution:

The standard form of an ellipse is

Where, a>b and 3a is the length of major axis.

We have,

Divide both sides by k.

Here, .

So, the length of the major axis is

Therefore, the value of k is 18.
