Step-by-step explanation:
In this case we have to perform a hypothesis test on the proportion of the people owning cats.
The claim is that the proportion is significantly different than 905, what means it can be greater or smaller than 90% to reject the null hypothesis. Because of that, the null hypothesis has to state an equality (H0:p=0.9).
The right answer is Option B:
Answer:
Tim
Step-by-step explanation:
The best description of the graph is offered by Tim:
"She drives at a variable speed for 2 minutes, then drives at a constant speed for 4 minutes, and finally stops at the parking area for the next 2 minutes."
The slope of the graph is Kate's speed. When it varies, it means her speed is varying. When it is constant, it means her speed is constant. When the line is horizontal, the slope (and Kate's speed) is zero.

<em>Comment on the question</em>
The graph describes <em>Kate's</em> distance from home. The question asks about <em>Lisa's</em> motion. We have no idea whether any of the students are describing Lisa's motion, as there is no information provided about what Lisa's motion is.
