1. A coin is tossed 10 times and lands heads up 6 times and tails up 4 times. Are these results consistent with the expected 50-50 ratio? 1A. If the coin is tossed 100 times and lands head up 60 times and tails up 40 times, is the hypothesis acceptable?

A student randomly guesses at four multiple-choice questions. Each question has three possible choices. The random variable X denotes the number of correct answers. This experiment can be modeled as Oa) a normal experiment with mean 4 and standard deviation 1/3. O b) a normal experiment with mean 1/3 and standard deviation 4. O c) a binomial experiment with 3 trials and success probability 1/4. O d) a binomial experiment with mean 4 and standard deviation 1/3 O e) a binomial experiment with 4 trials and success probability 1/3.
6. DETAILS c) What is the probability that X = 31? It is known that 41% of new freshmen at State University will graduate within 6 years. Suppose we take a random sample of n=70 new freshmen at State University. Let X = the number of these sampled freshmen who graduate within 6 years. (Do not use a normal approximation for this problem. This is a binomial problem.) a) What is the probability that X < 29? b) What is the probability that 28 ≤ x ≤ 31? d) What is the expected value of X? e) What is the variance of X?

16. A soldier is parachute training. He jumps out of plane high enough that the pilot determines the soldier will land somewhere in an 240 foot radius land zone. The pilot forgot to mention to the soldier that the parachute has very little maneuverability (no steering) and there are 30 trees in the landing zone. Each tree from the air practically outlines a circle with a radius of 8 feet. What is the geometric probability that the soldier will land Area of Circle =ar? 240 ft a tree?
