Question

Make the appropriate conclusion. Choose the correct answer below. A. Reject Upper H 0. There is insufficient evidence to indicate blood lactate level is linearly related to perceived recovery at alphaequals0.10. B. Reject Upper H 0. There is sufficient evidence to indicate blood lactate level is linearly related to perceived recovery at alphaequals0.10. C. Do not reject Upper H 0. There is sufficient evidence to indicate blood lactate level is linearly related to perceived recovery at alphaequals0.10. D. Do not reject Upper H 0. There is insufficient evidence to indicate blood lactate level is linearly related to perceived recovery at alphaequals0.10.

Answer 1

A. Reject Upper H 0. There is sufficient evidence to conclude that a higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the alphaequals0.10 level of significance.

Step-by-step explanation:

H0: p1 = p2

Ha: p1 > p2

pcap = (101 + 72)/(489 + 625) = 0.1553

SE = sqrt(0.1553*(1-0.1553)*(1/489 + 1/625)) = 0.0219

Test statistic,

z = (101/489 - 72/625)/0.0219 = 4.1710

p-value = 0.0000

Reject H0

A. Reject Upper H 0. There is sufficient evidence to conclude that a higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the alphaequals0.10 level of significance.
