2. Heidi plays horseshoes. There were 60 innings in which she had a double in theprevious inning. In those cases, she subsequently had a double 42 times. There were 40innings in which she had a non-double in the previous inning. She subsequently had adouble 18 times.(i) Find the sample probabilities of getting a double following a double and of getting adouble following a non-double.(ii) Find the pooled probability and pooled standard error under the null hypothesis ofequal probabilities.(iii) Test whether the probability of getting a double following a double differs from theprobability of getting a double following a non-double.

From the given information, Thee are 60 innings in which she had a double in the previous inning. In…

According to New Jersey Transit, the 8:00 a.m. weekday train from Princeton to New York City has a 90% chance of arriving on time on a randomly selected day. Suppose this claim is true. Choose 6 days at random. Let Y = the number of days on which the train arrives on time. What is P(Y = 4)? Interpret this value. (0.90)4 (0.10)². There is a 0.66% probability that exactly 4 of the 6 trains arrive on time. (0.90) ¹ (0.10)². There is a 0.66% probability that at least 4 of the 6 trains arrive on time. This probability cannot be calculated because this is not a binomial setting. O()(0.90)+ (0.10)². There is a 9.84% probability that at least 4 of the 6 trains arrive on time. O()(0.90)4 (0.10)². There is a 9.84% probability that exactly 4 of the 6 trains arrive on time.

A tube of listerine tartar control toothpaste 4.2 ounces. As people use the toothpaste the amount remaining in any tube is random. Assume the amount of toothpaste remaining in the tube follows a uniform distribution. What is the probability that there is more than 1.5 ounces remaining in the tube?
Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct. If two different subjects are randomly selected without replacement, find the probability that they both lied.
