A 5% random sample is to be selected from the given sampling frame. Use this information together with the table of random numbers to answer the questions below.

(a) What is the sample size?

(b) Determine the population size.

(c) With the twelfth row and sixth column as the starting point, move to the left in a
cursive order to write down the first names of all the sample members.

(d) What random sampling method has been used to obtain the sample?

Ineed in figuring out this problem.

If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f-g)(x).

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) =
