(a) Look at the data below regarding the variables x = age of a Shetland pony and y weight of that pony. Is the value of Ir| large enough to conclude that weight and age Shetland ponies are correlated? Use a = 0.05. (Use 3 decimal places.) 3 12 25 25 60 95 140 174 180 critical r Conclusion Reject the null hypothesis, there is sufficient evidence to show that age and weight of Shetland ponies are correlated. Reject the null hypothesis, there is insufficient evidence to show that age and weight of Shetland ponies are correlated. Fail to reject the null hypothesis, there is insufficient evidence to show that age and weight of Shetland ponies are correlated. Fail to reject the null hypothesis, there is sufficient evidence to show that age and weight of Shetland ponies are correlated. (b) Look at the data below regarding the variables x = lowest barometric pressure as a cyclone approaches and y = maximum wind speed of the cyclone. Is the value of Ir| lan %3D enough to conclude that lowest barometric pressure and wind speed of a cyclone are correlated? Use a 0.01. (Use 3 decimal places.) 1004 975 992 935 980 928 40 100 65 145 68 152 r critical r Conclusion Reject the null hypothesis, there is sufficient evidence to show that lowest barometric pressure and maximum wind speed for cyclones are correlated. Reject the null hypothesis, there is insufficient evidence to show that lowest barometric pressure and maximum wind speed for cyclones are correlated. Fail to reject the null hypothesis, there is insufficient evidence to show that lowest barometric pressure and maximum wind speed for cyclones are correlated. Fail to reject the null hypothesis, there is sufficient evidence to show that lowest barometric pressure and maximum wind speed for cyclones are correlated.
