Is the average time to complete an obstacle course different when a patch is placed over the right eyethan when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed anobstacle course with a patch over one eye and then completed an equally difficult obstacle course with apatch over the other eye.

Blake and April are both taking AP Calculus, but they have different teachers who have two different grading systems. Blake is in Mr. Frey’s class and April is in Coach Smith’s class. Blake is mad because she thinks that with her averages, she would have a higher average in Coach Smith’s class. Given her averages below, what would be her overall average for each class?

Researchers wanted to determine whether fence lizards learned to avoid fire ants. To determine this, they gathered lizards from eastern Arkansas (where there were no fire ants), and from southern Alabama (which had been invaded by fire ants). The lizards were then exposed to fire ants, and researchers measured how long (in seconds) it took the lizards to flee. What does each dot represent? Choose the best answer. Choice 1:A difference in time to flee for a single lizard from Alabama, and a single lizard from Arkansas, assuming the null hypothesis is true. Choice 2:A difference in mean response times for one sample of lizards from Alabama, and one sample of lizards from Arkansas, which was likely to occur if the null hypothesis is true. Choice 3:A difference in response times for two lizards in our sample. Choice 4:The proportion of all lizards who will free from fire ants. Which Choice is most correct and why?

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near the shore. Location IV was 200 meters downstream from the discharge point and in midstream. The following table shows the results. Lower dissolved oxygen readings mean more pollution. Because of the difficulty in getting midstream samples, ecology students collecting the data had fewer of these samples. Use a 5% level of significance. Do we reject or not reject the claim that the quantity of dissolved oxygen does not vary from one location to another? Location I Location II Location III Location IV 7.6 6.3 4.6…

Emily is making two pizzas at home. For each pizza, she needs to prep the dough and put it intothe oven, which takes 8 minutes per pizza. In the oven, the pizza bakes for 6 minutes. Then,Emily takes the pizza out and slices it, which takes 2 minutes. The oven can only hold one pizzaat a time. How long will it take her to make the two pizzas?
