You want to study an agricultural treatment to remove a pest on citrus plants. Suppose you have a citrus farm. The presence of the pest is measured by the productivity of the plant. Suppose that before and after applying the treatment the productivity of 9 plants was measured. Measurements are in numbers of bags and are in the following table:

Find the confidence interval to see if there is an improvement in productivity with the treatment of the pest. Determine with 95% confidence the interval for the average difference in citrus productivity.

Before	35	28	33	42	38	43	36	26	35
After	38	33	37	41	40	44	39	28	39

Suppose an agricultural scientist plants two different types of corn seed to test the claim that...

Suppose an agricultural scientist plants two different types of corn seed to test the claim that they produce the same average yield. The seeds are planted on eight randomly selected plots of land, each of which has one half of the plot planted with Type 1 seed and the other half planted with Type 2 seed. Calculate a 95% confidence interval estimate for the mean difference between the yield for Type 1 seed (Population 1) and Type 2 seed (Population...

Suppose you want to study the effects of the number of students per classroom in algebra...

Suppose you want to study the effects of the number of students per classroom in algebra courses and students’ performance in algebra courses for high schools in Kansas. You collected a random sample and now you have data for the above two variables. You called them as number students (which refers to the number of students per classroom in algebra courses), and students performance (which refers to the students’ performance in algebra courses - measured as their final grade in...

You want to purchase agricultural land and enrolling the land in a conservation program offered by...

You want to purchase agricultural land and enrolling the land in a conservation program offered by your state water and soil resources board. This program pays landowners not to farm the land for a specified period of time. A requirement of the program is that you establish vegetation on the land that would benefit wildlife. The program provides cost-share funding to help landowners establish wildlife habitat. Your estimate that the costs and returns associated with purchasing the land, enrolling it...

A. Suppose you want to study the number of hours of sleep full-time undergraduate students at Belmont get each evening. To do so, you obtain a list of full-time undergraduate students at Belmont, obtain a simple random sample of ten students, and ask each of them to disclose how many hours of sleep they obtained the most recent Monday. What is the population of interest in this study? What is the sample? Explain why number of hours of sleep in...

In a study on the role of music and the growth of tomato plants, you planted 32 tomato plants. Half of the plants grew up without music, while the other half grew up with music. When the plants reached their full maturity you measured them and you obtained as an average 19.54 cm and 23.39 cm for the group without music and the group with music respectively. In addition, you have calculated the standard deviations of the two groups which...

Now you want to study the protein product of this mutant brat gene, and you want to introduce this human brat gene into a bacterial expression vector (one that can be expressed to make a protein in bacterial cells) in hopes of producing a large amount of the human mutant Brat protein. Should you use the genomic DNA or the cDNA version of this gene? Explain your reasoning.

A company has three manufacturing plants, and you want to determine whether there is a difference in the average age of workers at the three locations. The following data are the ages of five randomly selected workers at each plant. Perform a test to determine whether there is a significant difference in the mean ages of the workers at the three plants. Use α = 0.01 . Interpret on your findings. Plant A Plant B Plant C 29 31 27...

Suppose you are a farmer producing grain in a perfectly competitive agricultural market. You are currently in the long-run earning zero economic profit. In the blank under each situation presented below, write whether you would expect “entry of new firms” or “exit of incumbent firms” with respect to how each situation would affect the market price of wheat in the industry. Treat each situation separately. Hint: you may need to refer back to Chapter 2 on supply/demand. (Each blank is...

Suppose that you start with a normal deck of 52 cards and remove everything except the twos, threes, and fours. So you now have a deck of twelve cards consisting of four twos, four threes, and four fours. A card is drawn at random and replaced then another card is drawn at random and replaced. Make a probability distribution for the sum of the two numbers that are drawn. Hint: List all the possible sums of two cards given 4...
