This question is about designing an experiment to test the effectiveness of a new vegetable fertilizer at two different levels of concentration.
The experiment will include 30 test plots, half of which will be in the shade, with a control group to compare the results. Randomization will be used to ensure that the results are not biased.

- Tire pressure (psi) and mileage (mpg) were recorded for a random sample of seven cars of thesame make and model. The extended data table (left) and fit model report (right) are based on aquadratic model. Calculate R2. Describe what this value means in the context of the problem.When exposed to an infection, a person typically develops antibodies. The extent to which theantibodies respond can be measured by looking at a persons titer, which is a measure of the number of antibodies present. The higher the titer is, the more antibodies that are present. The data in Table represent the titers of 11 ill people and 11 healthy people exposed to the tularemia virus in Vermont. Is the level of titer in the ill group greater than the level of titer in the healthy group? Use the α = 0.10 level of significance.The average number of red blood cells per cubic mm in humans is about 5 million. We'll let μ = 5,000,000, and σ = 500,000. Give the values for the number of red blood cells for the middle 80% of people. Give the values for the number of red blood cells for the middle 60% of people. Give the 80th percentile.
- The pathogen Phytophthora capsici causes bell peppers to wilt and die. Because bell peppers are an important commercial crop, this disease has undergone a great deal of agricultural research. It is thought that too much water aids the spread of the pathogen. Two fields are under study. The first step in the research project is to compare the mean soil water content for the two fields. Units are percent water by volume of soil.Your daughter is wasting my husband's money by trying to collect 6 rare photocards from a foreign album. Calculate the average number of albums she needs to buy in order to get all the 6 collectibles. Use the three trials shown below for your simulation.(Note: Treat the data vertically, and in order).Sandy is running a small business working on hand-made accessories. She has a customer, Jenny, who orders different items every day. After receiving Jenny’s order, Sandy packs a parcel for Jenny and makes delivery through the delivery service in her building. The delivery fee of a parcel is calculated based on the weight of the content, which is $0.033 per gram. According to Sandy’s record, the delivery fee of Jenny’s daily parcel follows a normal distribution with mean $66 and standard deviation $12.4. A parcel is classified as a deluxe parcel if the delivery fee is more than $100. It takes 2 working days to deliver a deluxe parcel and 4 working days to deliver the other parcel. (a) What is the probability that a Jenny’s parcel would be delivered in 2 working days? (b) There are 10% of the delivery fee of Jenny’s parcel are less than $K. What is the value of K? Instead of delivering Jenny’s parcel every day, Sandy is planning to combine two days’ order and pack Jenny a parcel for…

- The pH of a liquid is a measure of its acidity or alkalinity. Pure water was a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are alkaline. A biologist was interested in testing the purity of lake water in Florida. A random sample of 58 lakes was taken, and the pH of water in each lake was recorded. The sample of lakes had an average pH of 6.567 with a standard deviation of 1.861. Using a significance level of 0.01, is there evidence the mean pH of Florida lakes is not neutral? What hypotheses should be tested?
