The mean value of land and buildings per acre from a sample of farms is $1200, with a standard deviation of $200 The data set has a bell-shaped distribution Assume the number of farms in the sample is 76
(a) Use the empinçal rule
estimate the number of farms whose land and building values per acre are between $1000 and $1400
farms (Round to the nearest whole number as needed)
(b) i 29 additional farms were sampled, about how many of these additional farms would you expect to have land and building values between $1000 per acre and $1400 per acre?
farms out of 29 (Round to the nearest whole number as needed)

Amanufacturing firm has been averaging 16.8 orders per week for several years. however, during a recession, orders appeared to slow. suppose the firm’s production manager randomly samples 31 weeks and finds an average of 15.6 orders with a standard deviation of 2.3 orders. using a 0.025 significance level, test whether the mean number of orders has decreased. type the full 5 step procedure into the answer box, then for multiple choice practice, answer the following: 1. what is the name and symbol of the parameter that you are testing? 2. what is the symbol and value of the point estimate of that parameter? 3. what distribution are you using to test this parameter? 4. what is the critical value? 5. what is the test statistic value? 6. what is the p-value?
