During this past tennis season, the Team A won 177 of 200 games
while the Team B won 117 of 130 games. We’re interested in
determining if Team A is significantly worse than Team B. At a 5%
level of significance, conduct the appropriate hypothesis test.
a. Ho: pA = pB Ha: pA
pB
b. Test statistic: = Round to 2
decimals.
c. p-value = Round to 4 decimals.
d. Interpretation of the p-value: If the null hypothesis
is , then there is a probability...

(4)(a)An army recruiting center knows from past experience that
the weight of army recruits is normally distributed with a mean, u,
of 80 kg. and a standard deviation of 10 kg. The recruiting center
wants to test, at the 1% level of significance, if the average
weight of this year’s recruits is significantly different from past
observations. To do this, it takes a random sample of 25 recruits
and finds that the average weight for this sample is 85 kg....

I have a question, which I cannot find the correct solution to
from my book.
