2. we are managing a large soy bean farm. to estimate our revenues for the coming year, we need to estimate our crop yield. soy bean yields are measured by pods/plant. we are planning for a yield of 40 pods/plant. we take a random sample of 81 soy bean plants and get a sample yield of 41.5 pods/plant with a sample standard deviation of 7.2 pods/plant. a. use minitab to find the correct t multiplier, then compute by hand a 90% confidence interval for our population yield based on this sample. confirm your answer using minitab’s 1-sample t function. (note that yield in pods/plant gives a mean, thus a t interval is used.)
