Question

Data on 19 randomly selected athletes was obtained concerning their cardiovascular fitness (measured by time to exhaustion running on a treadmill) and performance in a 20-km ski race. Both variables were measured in minutes and a regression analysis was performed Ski- 88 -1.8*Treadmill Coefficients Estimate Std. Error (Intercept) Treadmill 0.21 1.8 0.657 Is there sufficient evidence to conclude that there is a linear relationship between cardiovascular fitness and ski race performance? The test statistic is * Preview The p-value is between and At the 5% significance level, we reject hypothesis and conclude that there is sufficient to conclude that there is a linear relationship between cardiovascular fitness and ski race performance the null evidence Post this question to forum

Explanation / Answer

Test Statistic = -1.8/0.657 = -2.74

P value = P(t<-2.74)+P(t>2.74)

= 0.0140

So,P value is between 0.01 and 0.03
