Question: Hand span is defined as the maximum distance between the tips of the thumb and little finger. Hand span (cm) was compared for a random
Hand span is defined as the maximum distance between the tips of the thumb and little finger. Hand span (cm) was compared for a random sample of 87 boys and 103 girls of the same age, with the boys' mean hand span found to be 22.53cm and the girls' mean hand span 20.02cm. Is the difference in means significant? Using a calculated test statistic value of t = 10.74 and P-value = 0.000, choose the most correct conclusion (use = 0.05).
A)Reject H0 since P-value > 0.05 - there appears to be no significant difference in the mean hand spans between boys and girls
B)Fail to reject H0 since P-value > 0.05 - there appears to be no significant difference in the mean hand spans between boys and girls
c)
Reject Ha since P-value < 0.05 - there is insufficient evidence that the mean hand span for boys is greater than the mean hand span for girls |
D)Fail to reject H0 since P-value < 0.05 - there is evidence that the mean hand span for boys is greater than the mean hand span for girls
E)Reject H0 since the P-value < 0.05 - there appears to be a significant difference in the mean hand spans between boys and girls
