The heights of a certain population of corn plants follow a distribution with mean 145 cm and standard deviation 22 cm. (a) Suppose we were to choose a sample of size 16 at random from the population, what would be the mean and standard deviation of the sample average? (b) Suppose we were to choose a sample of size 16 at random from the population, what would be the distribution of the sample average? (c) Suppose we were to choose...

Heights were measured for a random sample of 13 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 31 centimeters and 7 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean u. Based on the sample, can it be concluded that u is different from 30 centimeters? Use the 0.1 level of significance. Perform a two-tailed test. Then fill in the...

3. To test the hypothesis that all four types of plants reach the same maximum height, scientists selected six greenhouses. In each greenhouse, one of each of four types of plants was planted. The plant heights (in centimeters) are recorded as following: Greenhouse Plant type Plant type 2 Plant type 3 Plant type 4 14.7 13.5 12.8 19.8 16.7 17.7 18.2 20.3 15.5 21.9 19.8 21.0 21.4 22.1 20.8 16.4 15.4...

Since early Roman days, people have used greenhouses to grow plants—particularly to enjoy fruits and vegetables out of season. But not until the 1990s did greenhouses begin to gain popularity in the United States. The timing couldn’t be better. The amount of farmable land per capita in the world continues to shrink, and over the next 50 years, world population is expected to increase by 3 billion. At the same time, economists estimate the demand for farm products will double....

Heights were measured for a random sample of 10 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 31 centimeters and 12 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean J. Based on the sample, can it be concluded that ju is different from 42 centimeters? Use the 0.05 level of significance. Perform a two-tailed test. Then fill in the...
