1. Agronomists measured the yield of a variety of hybrid corn in 16 locations in the units of bushels per acre and formed a frequency distribution table with classes 150 - 180, 180 - 210, 210 - 240, 240 - 270 and 270 - 300. If the frequencies for the first two classes are 4 and 5 and the frequencies for the last two classes are 2 and 2,

1a. what would be the frequency for the class 210 - 240?

1b. Based on the above data, how many locations have yield less than 210 bushels?

1c. Continuing with the above data, what proportion of locations have yields in the class of 240 - 270?

1d.What is the sample size in the above study

Corn yield. The mean yield of corn in the United States is about 135 bushels per acre. A survey of 50 farmers this year gives a sample mean yield of x ̅= 138.4 bushels per acre. We want to know whether this is good evidence that the national mean this year is not 135 bushels per acre. Assume that the farmers surveyed are an SRS from the population of all commercial corn growers and that the standard deviation of the...

Corn. The average yield of corn (bushels per acre) for Iowa counties during 2019 can be described by a Normal distribution with a mean of 180.5 bushels per acre and a standard deviation of 16.8 bushels per acre. Use the 68-95-99.7 Rule (Empirical Rule) to answer the following questions. (a) Create a well labeled normal curve for the average corn yield (bushels per acre) for Iowa counties during 2018. On this graph numerically label the mean (iv), the center 68%...

(1 point) An agricultural field trial compares the yield of two varieties of corn. The researchers divide in half each of 10 fields of land in different locations and plant each corn variety in one half of each plot. After harvest, the yields are compared in bushels per acre at each location. The 10 differences (Variety A - Variety B) give x¯=3.35 and s=6.99. Does this sample provide evidence that Variety A had a higher yield than Variety B? (a)...

10. Suppose the development of new drought-resistant hybrid seed corn leads to a 50% increase in the average yield per acre without increasing the cost to the farmers who use the new technology. If the conditions in the corn industry are approximated by the price-taker model, which of the following will be likely to occur? (More than one answer is correct, list all correct answers) a. The market supply of corn will increase. b. The supply of soybeans (a close...

A botanist has produced a new variety of hybrid wheat that is better able to withstand drought than other varieties. The botanist knows that for the parent plants, the proportion of seeds germinating is 80%. The proportion of seeds germinating for the hybrid variety is unknown, but the botanist claims that it is 80%. To test this claim, 400 seeds from the hybrid plant are tested, and it is found that 312 germinate. Use a 5% level of significance to...
