(04.02 MC)  A coin is weighted so the probability of heads is 0.65. The coin is tossed 15 times, and the number of times heads shows is recorded. This procedure is repeated 100 times with the number of times heads shows noted each time. What kind of distribution is simulated? (4 points)

(04.02 MC)  Suppose 70% of jurors come to a just decision. In a jury of ten people, what is the probability more than half come to a just decision? (4 points)

(04.06 MC)  The mean household income for a certain state is $69,000 with a standard deviation of $10,000. Assuming a Normal distribution, about 95 percent of all households have an income over what amount? (4 points)

(04.06 MC)  The 400-meter race times at a state track meet are normally distributed with a mean of 52.71 seconds and a standard deviation of 3.8 seconds. Using the Standard Normal Probabilities table, what is the approximate probability that a runner chosen at random will have a 400-meter time less than 53.4 seconds? (5 points)

Core muscles are made up of: 

More longitudinal reinforcement is required where bending moments have the largest magnitude.

(04.02 MC)  Suppose 65% of jurors come to a just decision. In a jury of ten people, what is the probability more than half come to a just decision? (4 points)

Based on class discussion what is the best way to test overall flexibility?  

(06.07 MC)  A doctoral student wants to determine the relationship between steps per minute and the time it takes to walk 100 feet in minutes. Thirty trials are completed and the correlation coefficient between steps per minute and time in minutes is determined to be -0.543. Therefore, fewer steps per minute were related to longer time spans. How is the correlation affected if the units for time are changed from minutes to seconds? (3 points)

(04.06 MC)  The 100-meter race times at a state track meet are normally distributed with a mean of 14.62 seconds and a standard deviation of 2.13 seconds. Using the Standard Normal Probabilities table, what is the approximate probability that a runner chosen at random will have a 100-meter time less than 15.5 seconds? (5 points)
