Suppose you computed r = 0.563 using n = 31 data points. Using the critical values table below, determine if the value of r is significant or not. df 1 2 3 4 5 6 7 8 9 10 CV (+ and -) 0.997 0.950 0.878 0.811 0.754 0.707 0.666 0.632 0.602 0.576 Select the correct answer below: df 11 12 13 14 15 16 17 18 19 20 CV (+ and -) 0.555 0.532 0.514 0.497 0.482 0.468 0.456 0.444 0.433 0.423 df 21 22 23 24 25 26 27 28 29 30 CV (+ and -) 0.413 0.404 0.396 0.388 0.381 0.374 0.367 0.361 0.355 0.349 Or is significant because it is between the positive and negative critical values. Or is not significant because it is between the positive and negative critical values. Or is significant because it is not between the positive and negative critical values. Or is not significant because it is not between the positive and negative critical values. df 40 50 60 70 80 90 100 CV (+ and -) 0.304 0.273 0.250 0.232 0.217 0.205 0.195

The following histogram shows the exam score for a pre algebra class use this histogram to answer the questions. Find the number of students that took this exam.

First find the MAD for each pair of values, a and ß. Coal Production (thousands of tons) 434,330 Year 1. 420.427 3. 439,044 4 477 200 504.182 526.949 7. 546,822 564.884 556,711 8 10 570,975 The total number of thousands of tons of coal produced per year over a 10-year period for a certain region is provided in the accompanying dataset. Use double exponential smoothing to determine which pairs of values for a and B minimize MAD for this dataset a=0.1, p=0.8, a = 0.4. B 0 2; a=0.9, = 0.6 Click the icon to view the coal production data
