Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information: x 1 2 3 4 5 y 14.2 17.7 14.4 19.6 20.0 Σx = 15; Σy = 85.9; Σx2 = 55; Σy2 = 1,506.45; Σxy = 271.2 (a) Find x, y, b, and the equation of the least-squares line.

Two horses A and B were tested according to the time (in seconds) to run a particulat track with the following result: Horse A 28 30 32 33 33 29 34 Horse B 29 30 30 24 27 29 Test whether you can discriminate between two horses. You can use the fact that 5 percent value of t for 11 degrees of freedom is 2-20.

Do larger universities tend to have more property crime? University crime statistics are affected by a variety of factors. The surrounding community, accessibility given to outside visitors, and many other factors influence crime rate. Let x be a variable that represents student enrollment (in thousands) on a university campus, and let y be a variable that represents the number of burglaries in a year on the university campus. A random sample of n = 8 universities in California gave the following information about enrollments and annual burglary incidents.
You take a sample of n = 50 rats and you put them in three different cages: On day 1, they are in a cage that is in a room with a 65-degree temperature. On day 2, they are in a cage with a 70-degree temperature. On day 3, they are in a cage with a 75-degree temperature. For each rat, you determine at which of the three temperatures they spent the most time running on their wheel. Then, for each different temperature, you determine the number of rats (the frequency of rats) that ran the most at that temperature. You discover the following frequencies: At 65 degrees, 22 rats ran the most of any day. At 70 degrees, 18 rats ran the most of any day. At 75 degrees, 10 rats ran the most of any day. You want to test a null hypothesis that says rats are equally likely to run the most at any of the three temperatures. What kind of hypothesis test should you do?

The chemical benzene is highly toxic to humans. However, it is used in the manufacture of many medicine dyes, leather, and coverings. Government regulations dictate that for any production process involving benzene, the water in the output of the process must not exceed 7,950 parts per million (ppm) of benzene. For a particular process of concern, the water sample was collected by a manufacturer 25 times randomly and the sample average x was 7960 ppm. It is known from historical data that the standard deviation o is 100 ppm. (a) What is the probability that the sample average in this experiment would exceed the government limit if the population mean is equal to the limit? (b) Is an observed x = 7960 in this experiment a firm evidence that the population mean for the process exceeds the government limit? Assume that the distribution of benzene concentration is normal.
MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis. Professor Diff E. Cult wonders if male and female students earn significantly different grades when taking the same course with the same instructor. He randomly samples 160 males and 100 females from selected classes. The males receive 20 As, 32 Bs, 70 Cs, 30 Ds, and 8 Fs. The females receive 20 As, 28 Bs, 30 Cs, 10 Ds, and 12 Fs. His hypothesis is that gender and grades are related. Choose the type of test you should use to test this hypothesis? Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).

A researcher is investigating the effects of three different fertilizers (A, B, and C) on the growth of tomato plants. The height of the plants (in inches) is measured after one month using a sample of four plants for each fertilizer: Fertilizer A: [12, 14, 15, 13] Fertilizer B: [16, 17, 15, 18] Fertilizer C: [10, 11, 12, 9] Perform a one-way ANOVA to determine if there is a significant difference in the mean height of the tomato plants among the three fertilizers at a 5% significance level.

A gum ball machine contains 24 gum balls. Some are purple and the rest are yellow. There are 5 times as many purple gum balls as yellow. Because the purple gum balls are slightly smaller than the yellow, each purple gum ball is 3 times as likely to be dispensed as each yellow gum ball. An experiment consists of the machine dispensing one gum ball. Let each gum ball be considered one outcome. 1. What weight should be assigned to each purple gum ball? 2. What is the probability of the event that a yellow gum ball is dispensed?
Phosphorous is a chemical that is found in many household cleaning products. Unfortunately, phosphorous also finds its way into surface water, where it can harm fish, plants, and other wildlife. Two methods of phosphorous reduction are being studied. At a random sample of 7 locations, both methods were used and the total phosphorous reduction (mg/L) was recorded. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer. Things that are labelled i underneath a b c, etc are all part of that part.
