Captain Ben has a ship, the H. M.S Crimson Lynx. The ship is four furlongs from the dread pirate Umaima and her merciless band of thieves. If his ship hasn't already been hit, Captain Ben has probability \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction of hitting the pirate ship. If his ship has been hit, Captain Ben will always miss. If her ship hasn't already been hit, dread pirate Umaima has probability \dfrac{1}{2} 2 1 start fraction, 1, divided by, 2, end fraction of hitting the Captain's ship. If her ship has been hit, dread pirate Umaima will always miss. If the Captain and the pirate each shoot once, and the pirate shoots first, what is the probability that both the pirate and the Captain hit each other's ships?

Atest of sobriety involves measuring the subject's motor skills. a sample of 31 randomly selected sober subjects take the test and produce a mean score of 64.4 with a standard deviation of 2. a claim is made that the true mean score for all sober subjects is equal to 65. for each part below, enter only a numeric value in the answer box. for example, do not type "z =" or "t =" before your answers. round each of your answers to 3 places after the decimal point. (a) calculate the value of the test statistic used in this test. test statistic's value = (b) use your calculator to find the p-value of this test. p-value = (c) use your calculator to find the critical value(s) used to test this claim at the 0.2 significance level. if there are two critical values, then list them both with a comma between them. critical value(s) =
