A study was done to see whether getting radio airtime and spending money on advertisements accurately predicts the number of album copies sold. A random sample of 200 artists’ albums were tracked on the number of times their songs play on the central radio station, how much money (in thousands) they spent on advertisements, as well as the number (in thousands) of album copies were sold. A record company wanted to determine if there was a positive relationship between album sales and the other two variables (money spent on advertisements and number of albums sold) sales advertisements airtime 330 10.256 43 120 985.685 28 360 1445.56 35 270 1188.19 33 220 574.513 44 170 568.954 19 70 471.814 20 210 537.352 22 200 514.068 21 300 174.093 40 290 1720.81 32 70 611.479 20 150 251.192 24 190 97.972 38 240 406.814 24 100 265.398 25 250 1323.29 35 210 196.65 36 280 1326.6 27 230 1380.69 33 210 792.345 33 230 957.167 28 320 1789.66 30 210 656.137 34 230 613.697 49 250 313.362 40 60 336.51 20 330 1544.9 42 150 68.954 35 150 785.692 8 180 125.628 49 80 377.925 19 180 217.994 42 130 759.862 6 320 1163.44 36 280 842.957 32 200 125.179 28 130 236.598 25 190 669.811 34 150 612.234 21 230 922.019 34 310 50 63 340 2000 31 240 1054.03 25 180 385.045 42 220 1507.97 37 40 102.568 25 190 204.568 26 290 1170.92 39 340 689.547 46 250 784.22 36 190 405.913 12 120 179.778 2 230 607.258 29 190 1542.33 33 210 1112.47 28 170 856.985 10 310 836.331 38 90 236.908 19 140 1077.86 13 300 579.321 30 340 1500 38 170 731.364 22 100 25.689 23 200 391.749 22 80 233.999 20 100 275.7 18 70 56.895 37 50 255.117 16 240 566.501 32 160 102.568 26 290 250.568 53 140 68.594 28 210 642.786 32 300 1500 24 230 102.563 37 280 756.984 30 160 51.229 19 200 644.151 47 110 15.313 22 110 243.237 10 70 256.894 1 100 22.464 1 190 45.689 39 70 724.938 8 360 1126.46 38 360 1985.12 35 300 1837.52 40 120 135.986 22 150 237.703 27 220 976.641 31 280 1452.69 19 300 1600 24 140 268.598 1 290 900.889 38 180 982.063 26 140 201.356 11 210 746.024 34 250 1132.88 55 250 1000 5 120 75.896 34 290 1351.25 37 60 202.705 13 140 365.985 23 290 305.268 54 160 263.268 18 100 513.694 2 160 152.609 11 150 35.987 30 140 102.568 22 230 215.368 36 230 426.784 37 30 507.772 9 80 233.291 2 190 1035.43 12 90 102.642 5 120 526.142 14 150 624.538 20 230 912.349 57 150 215.994 19 210 561.963 35 180 474.76 22 140 231.523 16 360 678.596 53 10 70.922 4 240 1567.55 29 270 263.598 43 290 1423.57 26 220 715.678 28 230 777.237 37 220 509.43 32 240 964.11 34 260 583.627 30 170 923.373 15 130 344.392 23 270 1095.58 31 140 100.025 21 60 30.425 28 210 1080.34 18 210 799.899 28 240 1071.75 37 210 893.355 26 200 283.161 30 140 917.017 10 90 234.568 21 120 456.897 18 100 206.973 14 360 1294.1 38 180 826.859 36 150 564.158 32 110 192.607 9 90 10.652 39 160 45.689 24 230 42.568 45 40 20.456 13 60 635.192 17 230 1002.27 32 230 1177.05 23 120 507.638 0 150 215.689 35 120 526.48 26 60 26.895 19 280 883.877 26 120 9.104 53 230 103.568 29 230 169.583 28 40 429.504 17 140 223.639 26 360 145.585 42 210 985.968 17 260 500.922 36 250 226.652 45 200 1051.17 20 150 68.093 15 250 1547.16 28 100 393.774 27 260 804.282 17 210 801.577 32 290 450.562 46 220 26.598 47 70 179.061 19 110 345.687 22 250 295.84 55 320 2271.86 31 300 1134.58 39 180 601.434 21 180 45.298 36 200 759.518 21 320 832.869 44 140 56.894 27 100 709.399 16 120 56.895 33 230 767.134 33 150 503.172 21 250 700.929 35 190 910.851 26 240 888.569 14 250 800.615 34 230 1500 11 110 785.694 20 1) Test assumptions and make a decision (please provide written evidence to support your decision): 2) Inferential statistic(s) and p-value(s): 3) Decision:

1) Test assumptions and make a decision (please provide written evidence to support your decision):

2) Inferential statistic(s) and p-value(s):

3) Decision:

Statistics that allow for inferences or estimates about the population. Inferential statistics enable analysts come to conclusions about the population based on sample data. Inferential statistics cover the basics of inferential statistics, all kinds of hypotheses tests and their confidence intervals, design of experiments, and statistical power and errors. It also includes point estimation techniques, limit theorems, sampling distributions, approximations, and bounds. Correlation, regression, and association are also covered under inferential statistics to infer relationships between variables.
