You are interested in the conservation of an endangered plant. From previous surveys in typical years, you know that forest patches in your area have a 20% chance of containing the plant. After a particularly dry year you survey 25 patches and find that 2 of them have the plant. Do you have strong evidence that the plant is affected by dry years? State the null hypothesis in plain English and in mathematical notation Compute the P value What is your conclusion?

Step 1
The null hypothesis states that there is no relationship between dry years and the presence of the endangered plant. In other words, the probability of finding the plant in forest patches is the same regardless of whether it is a dry year or not. Show more…

Zoologists have been carefully observing an endangered species in the rain forest. They have noticed that the population P of the animal in the rain forest has decreased by 2.5% each year. Their observations indicated that 625 of the animals were initially in their study. Which rule can be used to estimate the population of the endangered animal over time? P = 625(0.75)^x P = 625(0.975)^x P = 625(1.025)^x P = 625(0.025)^x

A manufacturer of batteries wants to be reasonably certain that fewer than 5% of its batteries are defective. Suppose 300 batteries are randomly selected from a very large shipment, each is tested, and 10 defective batteries are found. Does this provide sufficient evidence for the manufacturer to conclude that the fraction of defective batteries in the entire shipment is less than .05? Use α=.01. a. What is the null and alternative hypotheses? b. What is the value of the test statistic? c. What is the p-value? d. Using α=0.01, do you reject or do not reject H₀? e. Write your conclusion in a complete sentence.

A researcher claimed that the smoking rate of younger citizens is higher than older citizens. In a random sample of 500 people aged 20-29, 115 were smokers. In a random sample of 400 people aged 30-39, 64 were smokers. At 0.01 level we want to test the researcher's claim. (a) Identify the null and alternative hypothesis (b) Calculate the value of the test statistics. (c) Find the critical value(s) and make a conclusion based on your value. (d) Find the P-value and make a conclusion based on the P-value.
