Answer:
The estimated value of the Batting Average is 0.229.
Step-by-step explanation:
In this case regression analysis is to performed to determine if there is a significant linear relationship for Batting Averages with Runs Score, Doubles, Triples, Home Runs and Strike Outs.
The independent and dependent variables are as follows:
<em>y</em> = Batting Averages
<em>x</em>₁ = Runs Score/Times at Bat
<em>x</em>₂ = Doubles/Times at Bat
<em>x</em>₃ = Triples/Times at Bat
<em>x</em>₄ = Home Runs/Times at Bat
<em>x</em>₅= Strike Outs/Times at Bat
The regression analysis can be performed in Excel.
Consider the regression output attached.
The regression equation is as follows:
Now estimate the Batting Average when Run Score (<em>x</em>₁) = 0.123, Doubles ( <em>x</em>₂) = 0.040, Triples (<em>x</em>₃) = 0.0045 , Home Runs ( <em>x</em>₄) = 0.009 and Strike Outs (<em>x</em>₅) = 0.189 as follows:
Thus, the estimated value of the Batting Average is 0.229.
From the information given, a right-tailed test using the z-distribution is appropriate.
At the null hypothesis, it is <u>tested if the class of statistics students is not significantly smarter than the general population</u>, that is, their mean IQ is of at most 100, hence:
At the alternative hypothesis, it is <u>tested if they are significantly smarter</u>, that is, their mean IQ is greater than 100, hence:
- We are testing if the mean is <u>greater than a value</u>, hence it is a right-tailed test.
- We have the <u>standard deviation for the population</u>, hence, the z-distribution is used.
