Answer:
lost = 9 games
and
won = 9 + 7 = 16 games
Step-by-step explanation:
Given that:
Total games played = 25
According to given condition:
lost = x
won = 7 + x ----------- eq1
x + x + 7 = 25
2x = 25 - 7
2x = 18
x = 9
So they lost = 9 games
and won = 9 + 7 = 16 games
i hope it will help you!

Answer:
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
Step-by-step explanation:
A. <em>One has 90% confidence that the sample proportion is equal to the population proportion. </em>
Confidence interval gives an interval estimate, not an equality
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
<em>Ture. </em>
<em>C.</em><em> One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>
Also true but <em>One has 90% confidence is not good interpretation. </em>
<em>D</em><em>. 90% of sample proportions will fall between the lower bound and the upper bound.</em>
<em>Lower bound and upper bound is given to estimate population proportion. </em>
