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, 
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.
Answer: -1/2
Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4
In y = mx + b; m is the slope
In this case, -1/2 is the slope
Answer:
1.16 to 2.75
Step-by-step explanation:
The mean salary (millions of dollars) for shortstops was 1.95.

The population mean for all baseball players was 1.85

The population standard deviation was 1.61.

Formula of confidence interval :
to 
z at 95% confidence level = 1.96
Substitute the values in the formula
Confidence interval :
to 
Confidence interval : 1.16 to 2.75
Hence the 95 percent confidence interval for these data is 1.16 to 2.75
