A botanist is studying a newly identified soybean disease. The botanist collected soil samples from all of the soybean fields in randomly selected states to see if there were significant differences the sulfur levels in fields with and without the disease.

1. What is the population?
-all u. s. soil
-all u. s. soybeans

2. What is the sample?
-selected u. s. soil
-selected u. s. soybean fields

3. What is the variable of interest?
-amount of sulfur in soil
-number of soybeans with the disease

4. How was the sample selected?

5. What method was used to collect the data?

6. Is the variable qualitative or quantitative?

7. Is the variable continuous or discrete?

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Problem 2. find the exact value of the remaining trigonometric functions. sketch theangle 8 for each problem. (3 points each)(a) tan 0 =o is in quadrant 2

The box plots show the distributions of the numbers of words per line in an essay printed in two different fonts.which measure of center would be best to compare the data sets? the median is the best measure because both distributions are left-skewed.the mean is the best measure because both distributions are left-skewed.the median is the best measure because both distributions are symmetric.the mean is the best measure because both distributions are symmetric
