Wilcoxon ranked test Body height and arm span are related quantities; tallerpeople generally have longer arms. One rule of thumb saysthat adult height is nearly equal to adult span. The armspans of 10 adults were measured in centimeters.Height 171 175 177 178 180 182 190 192 195 202Span 173 178 182 182 188 185 186 198 193 202At a =0.05, does the data indicate that the heights and armspans are equal?A.

[Simple Regression on House Price] Consider the following model you wish to estimate by using the OLS, Price = α + β sqrft + ε, where price is the house price in thousands of dollars and sqrft is size of house in square feet. The OLS result from Excel is as follows (see attached). At the 0.05 level of significance, is there enough evidence that the true population regression coefficient β is different from zero (i.e., H1: β≠0)? (a) Yes (b) No (c) We don’t have enough information to decide

[STATISTICS] How do you solve this?
cotinine levels measured in a group of nonsmokers exposed to tobacco smoke (n = 40, Mean = 60.58 ng>mL, s = 138.08 ng>mL) and a group of nonsmokers not exposed to tobacco smoke (n = 40, Mean = 16.35 ng>mL, s = 62.53 ng>mL). Cotinine is a metabolite of nicotine, meaning that when nicotine is absorbed by the body, cotinine is produced. Use a 0.05 significance level to test the claim that nonsmokers exposed to tobacco smoke have a higher mean cotinine level than nonsmokers not exposed to tobacco smoke. State null & alternative hypothesis What kind of test would this be - two tailed, left tailed or right tailed? The t test would be appropriate for testing this claim. Why is that?
