Find the $z_{\text {calc }}$ test statistic for each hypothesis test.

So far in the basketball season you have made 12 free throws out of the 20 free throws you have attempted, for a free-throw shooting percentage of $60 \%$. How many consecutive free-throw shots would you have to make to raise your free-throw shooting percentage to $80 \%$ ?

Very tall basketball players have a reputation of being bad free-throw shooters (even though their shots start closer to the rim!). Is this true? Here is a scatterplot showing the relationship between height (in inches) and free-throw percentage for all WNBA players in a recent season with at least 10 free-throw attempts. Describe the relationship between these two variables.

Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are randomly selected from those included in the table.

$$\begin{matrix} \text{ } & \text{McDonald's} & \text{Burger King} & \text{Wendy's} & \text{Taco Bell}\\ \text{Order Accurate} & \text{329} & \text{264} & \text{249} & \text{145}\\ \text{Order Not Accurate} & \text{33} & \text{54} & \text{31} & \text{13}\\ \end{matrix}$$

				If two orders are selected, find the probability that they

are both accurate. Assume that the selections are made without replacement. Are the events independent?

Express the indicated degree of likelihood as a probability value between O and 1. If you make a random guess for the answer to a true / false test question, there is a 50-50 chance of being correct.
