In 2011, the new york yankees won 97 out of 162 of their baseball games. is there sufficient evidence that the proportion of wins is greater than 0.5 at the α = 0.10 significance level?

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,

Hypothesis:

So, test statistic would be

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.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
