The national average SAT Score (for Verbal and Math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. If a random sample of 200 scores were selected and the sample mean were calculated to be 1050, would you be surprised? Explain.

Utility theory

The utility theory in economics is stated based on an individual’s preferences. It explains the behavior of individuals. Depending on the assumption, people can be ranked in order of their preferences. In other words, utility means the property in an object that brings benefit, advantage, pleasure, well-being, welfare, good, or happiness.

In python, for a sample data with 4 columns and 60 rows how do you find the parameters for the regression with the feature map (see attached) where we consider the loss function to be the square of residuals. Once this is done, how do you compute the empirical risk? I've attached some of the data below, it would be sufficient to see how you get results for the question using the above dataset. 1 14 25 620 -1 69 29 625 0 83 27 850 0 28 25 1315 1 41 25 2120 -1 153 31 1315 0 55 25 2600 0 55 31 490 1 69 25 3110 1 83 25 3535
When we discuss measures of center and spread, there are certain ones that go together, and certain ones that do not. If we talk about the center in terms of the mean, then spread is described using the ["", ""] . If we talk about the center in terms of the median, then the spread is described using the ["", ""] .
8. Commuting Times The U.S. Census Bureau reports that the average commuting time for citizens of both Baltimore, Maryland, and Miami, Florida, is approximately 29 minutes. To see if their commuting times appear to be any different in the winter, random samples of 40 drivers were surveyed in each city and the average commuting time for the month of January was calculated for both cities. The results are shown. At the 0.05 level of significance, can it be concluded that the commuting times are different in the winter?
