PLEASE HELP ME Pedro has created the function f(x) = the quantity of 3x plus 2, divided by 4 to represent the cost of texting on his current plan, where x represents the number of texts. Pedro discovers that, using the inverse function to solve for x = 32, he can predict how many texts he can use for $32. Explain to Pedro how to find the inverse function, using complete sentences. Find the inverse function, then use it to find how many texts he can send for $32. (10 points)

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) =
