4.The amount of atmospheric radiation to which a person is exposed to while flying by jet across the country is considered a random variable with an approximate normal distribution. On a New York to Los Angeles flight, this distribution has an assumed mean of 5.2 mrem, with a standard deviation of 0.615. What is the probability that a randomly selected individual on such a flightis exposed to more than 6.0 mrem (millirem) of atmospheric radiation?

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) =
