If the coefficient of localization for students spending in public schools (per capita at country level) in NC is close to 0, the distribution of student spending in the state is: (a) evenly spread across the 100 counties (b) concentrated in some countries (c) unevenly spread across the state (d) none of the above

6) A (real) published study in 2018 plotted the school grade distribution of female (red) and male (blue) students for STEM (science, technology, engineering, math) and non-stem subjects. The vertical line of "top 25%" means among the top 25% in percentile for all students, female to male ratio is 1.1 to 1 for STEM subjects (left), and female to male ratio is 1.3 to 1 for non-STEM subjects (right), and so on.

A researcher is interested in determining if the model used for the distribution of main economic concerns in the year 2003 for residents in a certain county can still be used in the year 2004. A sample of 370 residents from that county was surveyed in 2004. The following table displays the model for the distribution of economic concerns for the year 2003 and the observed number of sampled respondents in the survey for the same economic concerns for the year 2004. Economic concern 1: Jobs 2: Medical care 4: Housing Total 3: Higher education Model from 2003 5% 36% 27% 32% 100% Counts in 2004 25 138 116 91 370 Under the null hypothesis that the model from the previous year can still be used, what is the distribution of the chi-square statistic? ○ x ²(2) O x ²(3) O x ²(4) O x²(1)

Mariah Jacobsen is the marketing manager at ABC Electronics, a major consumer electronics supplier in the northwest. Over the last five years, sales of the company's flagship product - the Wizer Anonymizer (the WA) - have been 45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so. Ms. Jacobsen believes that the distribution of the WA's sales is normal with a standard deviation of 1500 units. If she were asked to make a forecast of next year's sales to upper management, what is the likelihood that she would be correct if she predicts sales between 43000 and 46000?
The figure above shows three different panels examining the relationship between average price and type of avocado.a)Compare the distributions of the average prices for the conventional and organic avocados. In particular, compare their central locations, spreads and skew to conclude whether there is evidence in this data that the average prices of organic avocados is different from those of conventional avocados.
