It is cоmmоnly believed thаt аthletes hаve lоwer resting heart rates than non-athletes. To investigate this claim, resting heart rates were measured for two independent random samples: n1 =25 athletes with a sample mean of =58 bpm and sample standard deviation s1 =9. n2 =22 non-athletes with a sample mean of =64 bpm and sample standard deviation s2=11. Assume that the population variances are equal but unknown. Compute the test statistic. TI-84 online
