Step-by-step explanation:

897/7

897 cannot fit into 7 so move the decimal place over 3 times.

897 can go into 7,000 7 times

897/7000

-6279

________

721

In 2011, The New York Yankees won 97 out of 162 of their baseball games. Is there sufficient evidence that the proportion of win

Cloud [144]

Answer: It is sufficient evidence that it will reject the null hypothesis.

Step-by-step explanation:

Since we have given that

Number of players of baseball games = 162

Number of games won = 97

So, $\hat{p}=\dfrac{97}{162}=0.5988$

Hypothesis:

$H_0:p\leq 0.5\\\\H_a:p>0.5$

So, test statistic would be

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.5988-0.5}{\sqrt\dfrac{0.5\times 0.5}{162}}}\\\\z=2.514$

And the p-value = 0.006 at z=2.514.

Since p-value < α = 0.10 significance level.

Hence, it is sufficient evidence that it will reject the null hypothesis.
