Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers us
1 answer:
Answer:
(B) (0.396, 1.712)
Step-by-step explanation:
From the information given;
Confidence Interval = 0.95
Significance Level
The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:
=
From the regression coefficient, the estimated value of beta^ = 1.054

(a) The z-score is calculated by subtracting the population mean from the x value and dividing this difference by the standard deviation.
If Nolan played for 44 minutes in last week's game against fairview, then his z-score would be:
ANSWER: The z-score for Nolan's playing time against fairview is 1.33.
(b) Since the z-score for Nolan's playing time against fairview is 1.33, then we know that his playing time is 1.33 standard deviations from the mean. If you compare this to the fact that 95% of all data fall within two standard deviations from the mean (empirical rule), then Nolan's playing time would not be unusual compared to the typical playing time.
