Answer: D. minimizes the sum of the squared residuals
Step-by-step explanation: The ordinary least square method is often used in locating the trendine which best fits a graphical linear model. The best is one in which the sum of the squared residual is smallest. The residual refers to the difference between the actual and the predicted points. The sum of the squared differences is obtained and the trend line is positioned where the residual is minimum. Choosing a OLS, and minimizing the sum.of the squared residual, the error difference between the predicted and actual score is minimized or reduced, hence, improving the prediction accuracy of our model.
Answer:
20%
Step-by-step explanation:
We are asked to find the proportion of of scores in a normal distribution between the mean (z = 0.00) and z = +0.52.
We will use normal distribution table to find area under normal distribution curve corresponding to given score as:
Using normal distribution table, we will get:
Therefore, approximately 20% of scores in a normal distribution between the given z-scores.
Answer:
10 quarts
Step-by-step explanation:
There are 4 quarts to a gallon, and she bought 2 1/2 gallons, or 2.5 gallons, so she bought 4(2.5) = 10 quarts
The number of zeros in both the quotient are the same (both have 3 0's).
