Assume that the yield per acre for a particular variety of soybeans is N(µ, σ2 ). For a random sample of n = 10 plots, the yields in bushels per acre were 21.68 33.09 28.20 42.28 44.77 61.97 37.20 55.96 52.18 29.38 i. Give a point estimate for µ and σ. ii. Test you assumption of normality with Q-Q plot. Can you get a another point estimate of σ? iii. Find a 90% confidence interval for µ and an 90% upper-bounded confidence interval for µ.

The historical mean yield of soybeans from farms in Iowa is 32.9 bushels per acre. Following a dry summer, a random sample of 40 Iowa farms is taken and the mean yield was found to be 30.78 bushels per acre with a standard deviation of 4.3. A hypothesis test is run to test the claim that the true mean yield of the dry summer was less than the historical mean. Which is the correct alternative hypothesis to test this claim?...

1. Let W1, . . . , Wn be i.i.d. N(µ, σ2). A 100(1 − α)% confidence interval for σ2 is ( ([n − 1]*S2 ) / (χ21−α/2,n−1 ) , ([n − 1]S2) / ( χ2α/2,n−1) , where χ2u,k denotes the 100×uth percentile of the χ2 distribution with k degrees of freedom, S2 = (n − 1)−1 * the sum of (Wi − Wbar )2 (from 1 to n) is the sample variance and Wbar = n−1 * the sum...

An agribusiness performed a regression of wheat yield (bushels per acre) using observations on 22 test plots with four predictors (rainfall, fertilizer, soil acidity, hours of sun). The standard error was 1.18 bushels. (a) Find the approximate width of a 95% prediction interval for wheat yield. (Round your answer to 2 decimal places.) yˆiyi ± (b) Find the approximate width using the quick rule. (Round your answer to 2 decimal places.) yˆiyi ± (c) The quick rule gives a similar...

1) A farmer finds that if she plants 60 trees per acre, each tree will yield 40 bushels of fruit. She estimates that for each additional tree planted per acre, the yield of each tree will decrease by 2 bushels. How many trees should she plant per acre to maximize her harvest? 2)A baseball team plays in a stadium that holds 46000 spectators. With the ticket price at $10 the average attendence has been 19000. When the price dropped to...

A local agriculture producer had a wheat yield last year of 72 bushels per acre. The producer had an unusually productive year. The normal wheat yield on this particular farm is 38 bushels per acre with a variance (σ2) of 16 bushels per acre. What is the probability that the wheat yield this year will be within one standard deviation (±) of the mean? Hint: think Empirical Rule.

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%...

When Farmer Hoglund applies N pounds of fertilizer per acre, the marginal product of fertilizer is 1 -N/200 bushels of corn. If the price of corn is $4 per bushel and the price of fertilizer is $1.20 per pound, then how many pounds of fertilizer per acre should Farmer Hoglund use in order to maximize his profits?
