The following data show the rankings of 11 states based on expenditure per student (ranked 1 highest to 11 lowest) and student-teacher ratio (ranked 1 lowest to 11 highest). Use Table 1 of Appendix B.

State	Expenditure per Student	Student-Teacher Ratio
Arizona	10	11
Colorado	5	8
Florida	4	6
Idaho	2	11
Iowa	7	4
Louisiana	10	3
Massachusetts	1	2
Nebraska	8	3
North Dakota	9	7
South Dakota	10	6
Washington	4	9

a. What is the rank correlation between expenditure per student and student-teacher ratio (to 2 decimals). Enter negative values as negative numbers.

Rs=

b. At the .05 significance level, does there appear to be a relationship between expenditure per student and student-teacher ratio?

z=

-p value is? (to 4 decimals)

Conclusion:
- Select your answer -We can conclude that there is a significant relationship.We cannot conclude that there is a significant relationship.

The average expenditure per student (based on average daily attendance) for a certain school year was $10,337 with a population standard deviation of $1560. A survey for the next school year of 150 randomly selected students resulted in a sample mean of $10, 798. Find the 95% confidence level? Should the null hypothesis be rejected? please write in the computer.

An education publication claims that the mean expenditure per student in public elementary and secondary schools is at least $10,200. You want to test this claim. You randomly select 16 school districts and find the average expenditure per student. The results are listed below. At α = 0.01, can you say the mean expenditure is different either way from the amount in the publication? Assume the population is normally distributed. 9,242 10,641 9,763 9,545 9,847 9,851 8,935 9,784 10,065 10,377...

The results below are based on data collected as part of a student project for an introductory statistics class at UF. If there is more than one group/treatment, the first group mentioned is group 1. Data was collected to determine if the price of food items at Graham Oasis (a convenience store inside UF campus) is higher, on average, than at a Publix Supermarket located 2 miles away. The p-value was 0.000, and the confidence interval was ( 0.85, 1.62)....
