A biologist is studying the plant diversity in 15 million acres of the Sierra Nevada Mountains. He will count the number of species in 150 acres. Match the strategies to their corresponding sampling techniques.
-abcde The biologist classifies the Sierras into 10 different ecological types and then makes sure that the proportion of each ecological type from the sample is the same as the proportion of that of the population.
-abcde The biologist goes to 15 diverse locations that have 10 acres each and surveys all 10 acres for each of these 15 locations.
-abcde The biologist goes to his 150 favorite hiking places and looks at an acres along each trail.
-abcde The biologist enters the 15 million acres into a data base and had a computer randomly select 150 of these acres.
-abcde The biologist orders the 15 million acres by latitude and then surveys every 100000th acre on the list.

A farmer would like to evaluate Miracle Grow when used on his potted daisy plants. He sets up 20 plants in a room all facing the same window, obtaining the same amount of sunlight, and waters them identically each day. For a month, he monitors how much each plant grows. Then, he adds Miracle Grow to every pot and monitors how much each plant grows during a month with Miracle Grow. At the end of two months, he discovers that 14 plants grew more with Miracle Grow. Test the hypothesis that Miracle Grow increases plant growth (using an alpha level of .01).
a) Is this a one-tailed or two-tailed test? (
b) State the null hypothesis.
c) State the alternative hypothesis.
d) Find the critical value(s).
e) Calculate the obtained statistic.
f) Calculate the P-Value (significance) of the obtained statistic).
g) Make a decision.
h) What does your decision mean?
Use the 7 step method (or the 5 step method) According to the American Automobile Association, 31 million Americans travel over the Thanksgiving holiday. To determine whether to stay open or not, a national restaurant chain surveyed 125 customers at each of four locations to see if they would be traveling over the holiday. At α = 0.10, test the claim that the proportions of Americans who will travel over the Thanksgiving holiday are equal. Use the P-value method.

- Based on Angel et al. (2003). A fertilizer companyis trying to determine the cheapest fertilizer mix thatprovides desired amounts of nutrients. The mix ismade by combining the following fertilizers: SSA,SPO, GUR, TSP, KCI, FERT, and SPF. The mix cannot contain both GUR and TSP. The percentage ofpotassium (K), sulfur (S), calcium (Ca), sodium (Na)and phosphorus (P) in each fertilizer is listed in the fileP06_88.xlsx. For example, a pound of SSA is 16% Kand 26% Na. The mix must contain at least 600 poundsof K, 550 pounds of S, 750 pounds of Ca, 900 poundsof Na, and 750 pounds of P. The mix cannot containboth GUR and TSP, because if both are present in themix, the affect of other fertilizers is nullified. The costper pound (in cents) of each fertilizer is listed in thesame file.

- Dawn is a brand of dishwashing liquid owned by Procter & Gamble. Introduced in 1973, it is the best-selling brand of dishwashing liquid in the United States. One of the inactive ingredients in Dawn is sodium lauryl sulfate. If the detergent contains too much of this ingredient, it will not perform as intended. The production process is set so that each bottle of Dawn detergent contains, on average, 8% sodium lauryl sulfate. How many bottles of Dawn detergent should be sampled if the Procter & Gamble quality control engineer wants to be 96% certain of being within 3% of the true population proportion of sodium lauryl sulfate in bottles of Dawn?
