Of all the trees planted by a landscaping firm, 50% survive.
What is the probability that 7 or more of the 9
trees they just planted will survive? (Giver your answer correct to
four decimal places.)
Homework Answers
This will be a binomial distribution with parameters:
n = 9, p = 0.50
Hence,
P(7 or more)
= P(7) + P(8) + P(9)
= 0.0898

In an area having sandy soil, 60 small trees of a certain type were planted, and another 60 trees were planted in an area having clay soil. Let X = the number of trees planted in sandy soil that survive 1 year and Y = the number of trees planted in clay soil that survive 1 year. If the probability that a tree planted in sandy soil will survive 1 year is 0.5 and the probability of 1-year survival in...

The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 80% of planted seeds will germinate. Suppose the manufacturer is correct. If 10 seeds planted with the fertilizer are randomly selected, what is the probability that at most 7 of them germinate? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.

The heights of pecan trees are normally distributed with a mean of 10 feet and a standard deviation of 2 feet. Show all work. Just the answer, without supporting work, will receive no credit. (a) What is the probability that a randomly selected pecan tree is between 9 and 12 feet tall? (Round the answer to 4 decimal places) (b) Find the 80th percentile of the pecan tree height distribution. (Round the answer to 2 decimal places) (a) For a...

If a seed is planted, it has a 65% chance of growing into a healthy plant. If 129 randomly selected seeds are planted, answer the following. a) Which is the correct wording for the random variable? b) Pick the correct symbol: n Correct = 129 c) Pick the correct symbol: p Correct = 0.65 d) What is the probability that exactly 79 of them grow into a healthy plant? Round final answer to 4 decimal places. e) What is the...

3 7 8 9 10 11 12 13 The manufacturer of a fertilizer guarantees that, with the aid of the fertilizer, 75% of planted seeds will germinate. Suppose the manufacturer is correct. If 6 seeds planted with the fertilizer are randomly selected, what is the probability that more than 4 of them germinate? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places. (If necessary, consult a list of formulas.)

Refer to the following information for Questions 13 and 14. The heights of pecan trees are normally distributed with a mean of 10 feet and a standard deviation of 2 feet. 14. Show all work. Just the answer, without supporting work, will receive no credit (a) For a sample of 36 pecan trees, state the standard deviation of the sample mean (the "standard error of the mean"). (Round your answer to three decimal places) (b) Suppose a sample of 36...

Shawn is planting trees along his driveway, and he has 5 oaks and 5 redwoods to plant in one row. What is the probability that he randomly plants the trees so that all 5 oaks are next to each other and all 5 redwoods are next to each other? Express your answer as a fraction or a decimal number rounded to four decimal places.
