p = 0.2
n = 10
P(at least one is parasitized) = 1 - P(no one is parasitized) = 1 - (1 - 0.2)10 = 0.8926 (ans)

#4. You are visiting a rainforest, but unfortunately, your insect repellent has run out. As a result, at each second, a mosquito lands on your neck with probability 0.5. If a mosquito lands, it will bite you with probability 0.2, and it will never bother you with probability 0.8, independently of other mosquitoes. What is the expected time between successive bites?

7. In a study of insect physiology, eggs from a beneficial species of moth were put in boxes placed in chambers at different temperatures. There were 30 eggs placed into each box, and the number of eggs hatching after 30 days were counted. The first box at 10°C had 0 hatch, the first box at 15°C had 1 hatch, and the first box at 20°C had 25 hatch. The data is courtesy of Jim Nechols, Department of Entomology, Kansas State...

You are visiting the rainforest, but unfortunately your insect repellent ran out. As a result, at each minute, with probability 0.5, one mosquito lands on your neck, and with probability 0.5, no mosquito lands. If a mosquito lands, it will bite you immediately with probability 0.2, or leave immediately with probability 0.8. a) What is the expected time between successive bites? b) Now we look at each mosquito that lands on your neck, and assume that it bites you no...

Applying the Central Limit Theorem: The amount of contaminants that are allowed in food products is determined by the FDA (Food and Drug Administration). Common contaminants in cow milk include feces, blood, hormones, and antibiotics. Suppose you work for the FDA and are told that the current amount of somatic cells (common name "pus") in 1 cc of cow milk is currently 750,000 (note: this is the actual allowed amount in the US!). You are also told the standard deviation...

65% of a certain species of squash live after transplanting from pot to garden. You transplant 35 of these plants. Assume that the plants live *independently* of each other. Let X = the number of tomato plants that live What is the probability that exactly 22 of the 35 squash plants live?

An ecologist randomly samples 20 plants of a specific species and measures their heights. He finds that this sample has a mean of 13 cm and a standard deviation of 3 cm. If we assume that the height measurements are normally distributed, find a 95% confidence interval for the height of all plants of this species. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place (if necessary,...

3. You perform an experiment to determine the effects of temperature on development in an insect species. You do so by incubating randomly selected eggs and larvae at 4 different and constant temperatures and measure the length (in mm) of the third leg after the last immature ecdysis event, with results shown below (each cell represents an individual insect).
