WebApr 2, 2024 · The critical value is − 0.456. − 0.567 < − 0.456 so r is significant. r = 0.708 and the sample size, n, is 9. The df = n − 2 = 7. The critical value is 0.666. 0.708 > 0.666 so r is significant. r = 0.134 and the sample size, n, is 14. The df = 14 − 2 = 12. The critical value is 0.532. 0.134 is between − 0.532 and 0.532 so r is not significant. WebUse the significance level a = 0.05 to complete the following conclusions. The critical F value for factor A (years in military) is 3.97. Therefore, the main effect due to factor A is … WebR can be used to find the critical value for an F distribution for a given significance level. For examp find the critical value (the value above which you would reject the null hypothesis) for a = 0.05 wit dfbetween = 6 and df within = 56, then F1-0.05 is found with: qf (1-0.05, df1=6, df2=56) Enter this code into RStudio to confirm you obtain the value 2.266. clash of clans hack zip file free download
