Need will give 30 points the table shows how an elevator 500 feet above the ground is descending at a steady rate. which equation represents the height, h(t), of the elevator in feet, as a function of t, the number of seconds during which it has been descending? a h(t) = 5t + 500 b h(t) = 5t – 500 c h(t) = –5t + 500 d h(t) = –5t – 500

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) =
