Answer:
There is evidence to support the claim that there is a linear correlation between the heights and pulse rates of women
Step-by-step explanation:
given that the heights (in inches) and pulse rates (in beats per minute) for a sample of 11 women were measured.
correlation coefficient r = 0.7200
(two tailed test at 5% significance level)
r difference = 0.7200
Std error of r =
Test statistic t = r difference/std error = 3.1128
df =9
p value=0.012458
since p <alpha, we reject H0
There is evidence to support the claim that there is a linear correlation between the heights and pulse rates of women
