Fit a line to these data where the november snowfall is the independent variable and the december – may snowfall is the dependent variable. make a plot that superimposes this linear fit over the data pairs. based on the least squares fit of the line to these data pairs, could you use this tv weatherman’s rule to accurately forecast twin cities’ snowfall in the dec. – may period based on snowfall during the previous november’s snowfall?

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) =
